Actress Sienna Miller was spotted last week in Los Angeles, seeking comfort in Leonardo DiCaprio's arms, just two weeks after she made up with her ex-fiancée, actor Jude Law.

Miller, 24, was seen cozying up Wednesday night in the L.A.'s Mood Club to the Hollywood hunk, chatting and drinking for hours, looking completely oblivious to onlookers.

One reveler told Britain's The Sun newspaper: "Sienna was getting very cozy with him. They spent most of the night huddled in a corner. They looked like they were having a great time."

When they left the club, both Sienna and Leonardo made sure they would not be spotted together. The source added: "They both went to great lengths to make sure they were not photographed together."

Leonardo first split up with his girlfriend, Brazilian supermodel Gisele Bundchen, before 2005. The on-and-off lovers later got back together and appeared in each others' arms at the 2005 Oscars.

Last month, the couple broke up again and the actor has been single since then.
