Rose Byrne isn't interested in marriage.

The 'Bridesmaids' actress is currently single but insists she doesn't feel she is missing out by not settling down or having children yet.

She said: "Marriage doesn't interest me.

"I have two nephews so I get to see how fundamentally a baby changes everything. So for now, the nephews will do, thank you."

The 31-year-old beauty admitted she hates the attention she receives from men but isn't afraid to speak up and ask them to leave her alone.

She recalled: "I went to a concert in LA recently, to see The National.

"And this guy tried to hit on me, right there, as the band were playing, during a ballad.

"I told him firmly to take his hands off me and step away. I guess he thought I was some Australian exchange student."

Rose recently admitted she often rows with her "sensitive" male friends and can understand the theme of 'Bridesmaids', which explores the impact of a wedding on a group of pals.

She said: "I think friendships are like that, man or woman. I've had friends that go away, you kind of drift. My most sensitive friend is a male friend. If I can't come to his place, he'll hang up on me and I'll be be like, 'oh my God, are you kidding me right now?' Guys are more sensitive."
