Leonardo DiCaprio has apparently been seen getting close to model Petra Nemcova.

The actor, who is rumored to be engaged to model Bar Refaeli, partied with Petra at New York's Marquee nightclub on Friday.

Mandy Moore has been linked to many Hollywood bachelors - including Zach Braff, Andy Roddick and most recently DJ AM, but that doesn't mean she enjoys the perils of dating.

The singer and actress told PEOPLE magazine at the Hollywood premiere of her latest film "Because I Said So," co-starring screen legend Diane Keaton, that she prefers to be in a relationship.

They may no longer be together, but that doesn't mean they can't join forces for an important cause.

Andy Roddick was in Florida over the weekend to host the first annual Charity Celebrity Poker Tournament. The event took place at the Seminole Hard Rock Hotel and Casino in Hollywood where the tennis player was greeted by his ex, Mandy Moore, who showed up to lend a helping hand.
