London - Scarlett Johansson loves looking at her co-star's naked butt.

The 28-year-old actress - who is currently dating French journalist Romain Dauriac - has opened up about the perks of starring as Maggie the cat in the Broadway revival of Tennessee Williams’ Cat On A Hot Tin Roof and admits she has a hard time taking her eyes off her on-stage husband Ben Walker, who spends a lot of time wearing very little or nothing at all.

The blonde beauty told Broadway.com: “That is really one of the brighter points of my life. I have asked Ben at times, when I was having a more difficult day, to just leave it out there for a couple more moments, just to brighten my day a little bit. I think it adds a little bit of hope in an otherwise dismal situation.”

The actress - who was previously married to Ryan Reynolds - also revealed that the huge production is taking a toll on her and she is exhausted after performing every night.

She said: “After the show ends every night. I don't want to do anything but sit at home and watch reruns of The Golden Girls.”

Scarlett recently admitted she auditioned for Anne Hathaway's role in Les Miserables, but is no longer disappointed about not getting the part.

She said: “I sang my little heart out. The jazz-hands kid inside me was just over the moon! I auditioned with laryngitis. I did everything I could to, like, not have laryngitis.

“I think, looking at the film now, there's no possible way I ever could have topped that performance (by Anne Hathaway). It was perfect and I think fateful and meant to be.” - Bang Showbiz
