Jaden Smith has denied being in a relationship with Kylie Jenner.

The 14-year-old 'After Earth' actor - who stars in the movie alongside dad Will - insisted he's not dating the 'Keeping Up With The Kardashians' star after he was asked about their relationship by Ryan Seacrest on his KIIS-FM radio show.

He said: ''I love Kylie and I love [her sister] Kendall [Jenner]. They're just really good friends.

''We all just kind of hang out because we live in the same neighbourhood and they're really cool girls. I love hanging out with them. They're just friends.''

The young film star was seen earlier this week with the 15-year-old model wearing an 'Iron Man' outfit in New York and Kylie has also been quick to insist they are just good friends.

In an interview with E! News she said she loves being around him because he is so supportive and she admitted it's great hanging out with someone who she can relate to.

She said: ''He comes and supports me with everything that I do. It's refreshing. Some people don't understand and some people do.

''It's just great to have someone grow up in the same position as you and you can relate in that kind of way, so it's fun.''
