Beyonce starts a new “forehead frame” pose as she celebrates her little sister Solange’s 22nd birthday at a Hollywood Hills mansion on Monday evening.

It’s kinda similar to the Roc-A-Fella Hand Gesture, no?

Lindsay Lohan made a brief appearance at Solange’s party. Lohan’s DJ BFF Samantha Ronson also played music all night long. Ludacris, Ne-Yo, Mario and Destiny Child’s Michelle Williams also were in attendance.

Solange has a CD coming out soon called Sol-Angel and the Hadley St. Dreams, and is expected be released August 26.

Big-haired sisters Beyonce and Solange Knowles work the red carpet at Jay-Z’s $20 million 40/40 Club, a 24,000-square-foot sports bar and lounge at The Palazzo Resort-Hotel-Casino on Sunday night in Las Vegas, Nevada.

“I just want everyone to have a good time and not get caught up in the whole glitzy pretentious clubbing thing,” Jay-Z said. “But I’m up for a big night, and a big year next year. Good things are gonna happen.”

The 40/40 Club is named after one of sport’s most prestigious achievements — 40 home runs and 40 stolen bases in the same baseball season. The club will feature an eclectic menu including The Picnic (fried deviled eggs and southern-fried chicken sticks with the special 40/40 sauce).
