Sienna Miller's Topless Photos With Jamie Burke

Another day, another celebrity caught strippin' down outdoors. Sienna Miller is the latest victim, as she has been photographed sunbathing topless.

Online photographs have surfaced of Miller on a Mexican beach with her new love, model Jamie Burke.

Miller, the former flame of British actor Jude Law was seen with Burke on an isolated Mexican beach on February 19th, confirming rumors that they are an item.

An onlooker said: "They were like a couple of love-struck teenagers." Jamie, 21, is the son of a millionaire and has been romantically linked to Lindsay Lohan, Kate Moss and Courtney Love.

While shooting 'Factory Girl', it was reported that Sienna was romancing her co-star Hayden Christensen.

In the film, in which Sienna plays artist Andy Warhol's tragic muse Edie Sedgwick, the pair's sex scenes are so realistic they sparked speculation Sienna and Hayden romped for real.

According to AHN, Sienna and Jamie were spotted kissing earlier this month at the Gramercy Park Hotel in New York City. Neither party has confirmed the relationship.

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