(Cover) - EN Showbiz - Justin Timberlake partied into the early hours with Mila Kunis and Olivia Wilde over the weekend.

The heartthrob has been romantically linked to both actresses since he split from Jessica Biel earlier this year. Justin has insisted he is just friends with Mila and Olivia and the trio let loose at the Saturday Night Live after-party to celebrate Justin appearing on the popular television show. The star was spotted laughing and joking with the beauties and even left the party with them.

"He was chatting away [with] both Mila and Olivia. The two actresses then hung out together, and Olivia talked for a while with Bradley Cooper," a source told New York Post. "Olivia, Mila and Justin all left at the same time."

Even though it has been reported Justin has romanced Olivia and Mila, sources close to the star insist he isn't interested in dating anyone at the moment. The hunk became pals with Mila after they starred in Friends with Benefits, while he has known Olivia since they appeared in 2006 movie Alpha Dog.

"Justin is in movies with both actresses; they are friends," an insider added.

Other stars spotted at the bash included Lady Gaga, Drew Barrymore, Ashley Olsen, Emma Stone and Sigourney Weaver. (C) Cover Media
