Russell admits that although he's happy as can be with Katy, he misses having sex with random strangers and his comedy act isn't as much fun as it used to be.
He is quoted by E! Online as saying: “It's not as good, because you're away from your actual girlfriend and you can't have sex with all the people out there."
He joked that because he can't have meaningless sex with random women, he's been going through women’s underwear drawers for sexual kicks.
Speaking about TV host Meredith Vieira, he joked: "She's got some surprisingly erotic underwear. There's crotchless, peep-hole stuff going on in there!"
Katy and Russell are planning on tying the knot in a weeklong celebration this October in India. Do you think Russell has what it takes to stay faithful to Katy? Or will he become the new Tiger?
