Justin Bieber is "too young" to marry Selena Gomez.

The 'Boyfriend' hitmaker claims he is not yet old enough to get wed his actress and singer girlfriend Selena, but hopes she is not offended by his decision.

Asked by French newspaper Le Parisien if he has plans to propose, he said: "No, I'm too young. One day, I will get engaged, when I have found the right person in five or 10 years. It doesn't mean Selena is not the right person though! She's going to kill me if I say that!"

Justin admits being in a public relationship can be hard, but knows it is something he signed himself up for when he became famous.

He added: "It is not easy to be so young and to have a relationship with someone that doesn't stay private. But, well, I am a public personality, it is what I wanted, so I have to deal with it."

Selena has her problems with Justin too - she recently revealed a photograph of the pair kissing at a Los Angeles Lakers basketball game was really embarrassing for her.

She said: "It's the most humiliating thing that's ever happened to me, probably.

"They were showing these little elderly couples, and it was so cute. Then all of a sudden we're both looking up and we come on the screen and it's like... It was so awkward.

"It was so weird. I mean you have to kiss, right?"
