On-and-off-screen couple Zac Efron and Vanessa Hudgens look like tween royalty at the European premiere of High School Musical 2 at London’s O2 Arena on Sunday.

Vanessa paired her stunning strapless floor-grazing gown by Trina Turk with silver Prada mules while Zac wore his pride for London with a navy jacket with a UK flag inner-lining (aka Union Jack jacket).

Zac, 19, recently told People he can’t remember the first time kissing Vanessa, 18.

“I truly didn’t realize that there was not a kiss. It never stuck out to me,” he says.

V recalls there was a kiss, but “on the cheek [and] that’s as far as we got.”

“You guys, your memories are failing you,” director/choreographer Kenny Ortega said Friday at a press conference in London to promote High School Musical 2. “I went to their parents and asked for permission. I went to Vanessa’s mom first, and then to Zac’s mom second and said, ‘Do you mind if I request a kiss in the event that we want to use it for the end of the film?’ And we did it. Then, we all sort of decided that this wasn’t about that.”

“You seemed to enjoy it though,” Ortega said to Zac, who blushed but didn’t deny the comment. (The kiss never made the cut for the first film.)

Sickingly sweet couple Zac Efron and Vanessa Hudgens work the crowd for a meet-and-greet at London music store HMV Oxford St. on Wednesday.

Zanessa joined High School Musical 2 castmates Monique Coleman, Lucas Grabeel and Olesya Rulin for the CD & DVD signing.

Zac brought back the bangs! Loving Vanessa’s tunic!! And the rings seem to be in tact!!!

And if you haven’t already, check out Time magazine’s article on “How Zac Efron Became the Cutest Guy Ever.” He’s a good-looking theater geek!

And here’s another tidbit about Vanessa from the Teen Choice Awards: “Vanessa was totally psyched about getting a new pink CHI hair flat iron. She already had the CHI iron in black and blue. And she loved seeing her face on the Mattel Games’ High School Musical edition Uno cards saying: ‘You know you’ve made it big when you’re an Uno card!’ But she was squealed with delight when she overheard her song played on a nearby foot-tapping iDog: ‘That’s me! That’s me!’” BABY V!

ZANESSA SIGHTING!

Zac Efron and Vanessa Hudgens are seen out and about London, making appearances for High School Musical 2.

Vanessa made an appearance the UK show This Morning while Zac dropped by the ITV show This Morning.

Check out Zac’s new hair. It’s out of this world!!! But I can’t tell if that’s a good thing or bad thing. The gray/silver outfit is definitely working though!

Watch V’s appearance here!

The 2007 Teen Choice Awards red carpet was disappointing as stars darted into the Gibson Amphitheater before the show started. (Being conveniently placed at the butt end of the press line did not help one iota). Vanessa Hudgens ran right past me but I was lucky enough to scream out and ask her “Who are you wearing??” “Uhhh, Thread social” she yelled back! Likewise, Zac whizzed right by, merely smiling and waving to reporters.

My head was not in the game as the show kicked off but I just happened to poke my head out of the press tent at the right time. Not only did I see Vanessa backtsage, Zac was standing right besides her! What were the odds?!

It was all you crazy Zanessa shippers. You guys willed it to happen!

I approached Vanessa first, as I did interview her over the phone about a year ago.

Asking her if she reads JustJared.com, Vanessa replied, “Of course I’m familiar with it!”

“Your site is totally blowing up,” she gushed. “I love it!”

I didn’t want to interrupt Zac as he was talking to one of his handlers at the time, but he came right on over and introduced himself to me!

Zac shook my hand and commented on Just Jared, “Yeah man, continued success!”

Zanessa kindly obliged to hold up “I LOVE JUSTJARED.COM” signs under one condition.

“Don’t write anything mean!” Vanessa said. “I’ll be reading!”

Zac jetted off in Eco-Limo Chauffeur Service’s Toyota Prius (pictured below) while Vanessa and I chatted for a bit more.

Vanessa mentioned she has already started to field new music for her upcoming sophomore album. And she was off to do more press for High School Musical 2 in Europe. Of course V took one last picture before she took off…

Congrats to the cute couple, who picked up three surfboards each! Zac for Choice Male Hottie, Vanessa for Choice Music Breakout Artist and both for High School Musical 2’s record-breaking debut and Best TV Movie!

A big thanks to Zac and Vanessa for showing Just Jared some love. And to all the Zanessa fans — you guys are the greatest!

Vanessa Hudgens arrives at the 2007 Teen Choice Awards which is televised annually on Fox.

Vanessa came to fame in 2006 when she starred in the Disney Channel film, High School Musical.

Not only do High School sweethearts Zac Efron and Vanessa Hudgens share clothes, the couple also shares sunglasses!

Zac, 19, and Vanessa, 18, both wore the same two pairs of shades on various occasions this past year — Cruz Sunglasses by Dita and Ray-Ban Wayfarers.

Vanessa Hudgens gives paparazzi a big thumbs up as she gets down to business at a meeting in a Hollywood office building on Friday. The High School Musical star then grabbed lunch at Bob’s Big Boy Burgers with her father.

It was suspected that her mom, Gina Guangco, picked her up at Zac Efron’s home early Thursday morning in the Toyota. But maybe it was her dad!

BBV toted around the Balenciaga Giant, chatted on her iPhone (probably with Zac!), brought back her “Live in Love” bracelet, and wore two different pairs of shades throughout the day including a pair of Ray-Ban Wayfarers and Cruz Sunglasses by Dita.

ZANESSA!

Vanessa Hudgens leaves the home of on-and-off-screen partner Zac Efron early Thursday morning in Los Angeles.

It’s suspected that her mom, Gina Guangco picked her up in the Toyota.

Later in the day, Zac was spotted eating lunch at Sitton’s Diner in North Hollywood for about 30 minutes with a mystery male.

Per usual, the High School Musical star covered his face as he entered through the front of the restaurant and exited out the back.

Zac wore a blue tee supporting OmniPeace, an organization which contributes to one of Angelina Jolie’s favorite charities, the Millennium Project.
