Paris Hilton and Kevin Federline got friendly while partying together in Las Vegas.
The hotel heiress and Kevin, the estranged husband of Paris' one-time friend Britney Spears', were spotted "flirting" on Tao nightclub's dancefloor last Friday. "It didn't look as though either of them were thinking too much about Britney.
" Meanwhile, Britney - who entered rehab after a spate of wild partying with Paris - had a more sedate weekend. Wearing a cowboy hat and new brunette wig, the Toxic singer visited a Los Angeles tanning salon on Saturday. Britney - who has two sons, 19-month-old Sean Preston and seven-month-old Jayden James, with Kevin - befriended Paris immediately after filing for divorce from Kevin last November.
However, Britney was reportedly advised to severe ties with the socialite for the sake of her music career, after she was pictured looking worse for wear and photographed on four occasions without underwear.
