1 George Clooney's current girlfriend, actress Renée Zellweger, was hot and heavy last year with funnyguy Jim Carrey. They were even rumored to be engaged, but since then Renée has obviously moved onward and upward. Zellweger starred in the hit movie Bridget Jones's Diary this year and is set to star alongside Catherine Zeta-Jones in the upcoming Chicago.

2 Actress Kelly Preston, currently Mrs. John Travolta, was a girl about town in her single days, with involvements with Clooney as well as trouble-plagued actor Charlie Sheen, with whom she had a volatile relationship.

3 Dedee Pfeiffer co-starred on the sitcom Cybill (she was the married daughter). She used to date George Clooney; then he went on to star opposite her sister Michelle Pfeiffer in One Fine Day.

4 Currently the first lady of Hollywood, Julia Roberts is in the upcoming Ocean's Eleven with Clooney. Rumor has it that one of the reasons Benjamin Bratt broke up with her was an on-set romance with Clooney. She has since been seen with cameraman Daniel Moder, who reportedly left his wife for Julia.

5 It appears Jim Carrey has been struck with the Penélope Cruz syndrome - he gets involved with his co-star on pretty much every movie he makes. He married Lauren Holly (Dumb & Dumber), dated Renée Zellweger (Me, Myself & Irene) and is now reportedly involved with his new leading lady Laurie Holden (The Majestic).

6 Actor/director Ethan Hawke is on a roll these days, with four new movies, a book, and a second baby on the way with actress wife Uma Thurman. During his single days, paparazzi hounded Hawke when it appeared he was seeing Julia Roberts, who happened to be married to Lyle Lovett at the time.

7 Jennifer Esposito, who starred in Spike Lee's Summer of Sam with Mira Sorvino, dated Benjamin Bratt before he moved on to Julia Roberts. She can currently be seen in Don't Say A Word with Michael Douglas.

8 Currently starring with Johnny Depp in From Hell, Heather Graham's love life has been caught by paparazzi since she hit the Hollywood scene. Actor/director Ed Burns and actor Heath Ledger are just two of her prior boyfriends, but she's single for the moment.

9 British actor Gary Oldman has been involved with several actresses, including Isabella Rossellini and Uma Thurman, who he was married to in the early '90s.

10 Quirky, intense and somewhat off-kilter actor James Woods made tabloid
headlines in the late '80s when he accused the quirky, intense and somewhat off-kilter Sean Young of stalking him. The two had just finished shooting The Boost together and an intense on-set fling apparently turned ugly. Woods is now playing Drew Barrymore's dad in Riding In Cars With Boys opposite Lorraine Bracco.

11 From Hell star Johnny Depp has completely changed his lifestyle since his
earlier years as the tabloid poster boy for bad behavior. He had a long-term relationship with supermodel Kate Moss and was engaged to actress Jennifer Grey as well as Winona Ryder. Depp has now settled down in France with French actress/singer Vanessa Paradis and their daughter. These days he tries to make it into the press for his movies alone - and keeps his toned-down personal life very private.

12 The man behind Twin Peaks and Blue Velvet, director David Lynch had a well-publicized affair with Isabella Rossellini in the late '80s. His latest movie is the recently released Mulholland Drive.

13 David Duchovny, the former Agent Mulder on Fox's The X-Files, can currently be seen in Zoolander. Before settling down with wife actress Téa Leoni (The Family Man) and their daughter Madelaine, Duchovny dated actresses Sheryl Lee and Winona Ryder.

14 Jennifer Grey (Baby in Dirty Dancing), had a short-lived but critically acclaimed sit-com last year and in her personal life has been involved with both Johnny Depp and Matthew Broderick. She's the daughter of actor Joel Grey.

15 Matthew Broderick is the toast of Broadway these days. The Tony-winning
actor stars in The Producers with Nathan Lane. Off stage, he shares the limelight and his New York apartment with wife Sarah Jessica Parker, who stars in Sex and the City. In his single days, Broderick had relationships with actresses Helen Hunt and Jennifer Grey.
