Wearing a straw hat and over-sized shades, Britney Spears drops her white linen top and poses for the pictures in the front garden of one of her friend’s houses using only freshly picked flowers to cover her chest.

These scandalous pictures surfaced just moments after her 14-minute performance at the House of Blues. Oh Britney, Britney, Britney…

UPDATE: Apologies, images removed but still can be viewed here.

Sienna Miller, topless in all her glory, snuggled up to her new main man, musician Jamie Burke this past weekend in Tulum, Mexico.

Sienna, 25, and Jamie, 21, were all over each other. Jamie even whipped out his guitar and started serenading Sienna — Jude Law’s ex. One onlooker said, “They were like a couple of lovestruck teenagers. They seem totally in love.”

The pair met at a party to celebrate her latest film Factory Girl at a New York hotel at the beginning of this month.

Jamie Burke has been romantically linked to the likes of Kate Moss, Lindsay Lohan, and er, Courtney Love.

Sienna flew back to Los Angeles yesterday and will be attending the Oscars this Sunday.
