Scarlett Johansson and Ryan Reynolds have split up, so if you see her sitting alone at a bar, why not ask if you can buy her a drink?

Don’t know what to talk to her about? Ask her how her cat (Trooper) and chihuahua (Maggie) are doing. That wouldn’t be creepy at all.

Best known as a regular on “House, M.D.,” the 26-year-old Olivia Wilde is starring in “Tron: Legacy.” Maxim has ranked her on their “Hot 100″ list three times, including the #1 spot in 2009.

She was born in New York City but has dual citizenship in the United States and Ireland, where she attended acting school. She’s a natural blonde, but has said she feels more like a brunette and has found that people treat her differently.

She was born Olivia Jane Cockburn, and (wisely) took Wilde as her stage name. She eloped with her husband, who is the son of an Italian prince, when she was only 18.

Best known as Joan from the hit AMC show “Mad Men,” the 35-year-old bombshell from Knoxville has been bouncing around television (no pun intended) for the last decade. And get this — she’s naturally a blonde, but has been dying her hair since she was 10 years old.

You may know her as the spoiled Shannon from “Lost,” but Maggie Grace’s acting career is alive and well, as she starred as Liam Neeson’s daughter in “Taken” and has since landed a role in the Dwayne Johnson crime-thriller “Faster.”

Known for her pretty face and athletic build, Brittany Daniel starred on “The Game,” “Dawson’s Creek” and “Sweet Valley High,” and appeared in “Club Dread” and “Joe Dirt.” Now she’s starring in the new sci-fi action thriller, “Skyline.”

And get this: She’s a twin.

Here are a few pictures of Brittany throughout the years. She looks good no matter what she wears.
