Katie Holmes thinks her marriage to Tom Cruise is "weird".

The 'Batman Begins' star - who has four-year-old daughter Suri with the actor - admitted having so many people speculating on the couple's relationship can be strange, but she just tries to focus on their day to day lives.

She explained: "It's one of those things. My big concern is what does he have going, what do I have going, what are we going to do this weekend. It must seem weird, I guess, having so many people watching. It is weird. I get it. But you just, you know, smile and nod."

The actress - who married the 'Top Gun' star in November 2006 after a whirlwind 17-month romance - admitted she is in awe of her spouse's long career and often turns to him for acting advice.

Katie added to New York magazine: "We do collaborate on everything at home. But I mean, he's Tom Cruise! His body of work is incredible. Every movie he's done has done really well. I look back, and everything's a classic.

"I definitely come home and say to him, 'So, imagine a scene . how would you play it?' And he's helpful and sweet and gracious. He's quite an incredible human being."
