Josh Hutcherson joked it ''wasn't easy'' to share Jennifer Lawrence with Liam Hemsworth in 'The Hunger Games: Catching Fire'.

The 21-year-old star portrays the blonde beauty's character Katniss Everdeen's love interest Peeta Mellark in the adventure movie, but also shares an embrace with Liam's alter-ego, Gale Hawthorne, and Josh says it was tough to watch.

Speaking at the movie's world premiere in London's Leicester Square last night (11.11.13), he told BANG Showbiz: ''I didn't mind sharing Jennifer with Liam. It wasn't easy, but I didn't mind sharing.

''In this movie you get to see a lot more of Peeta and for me it's great, it's great to be able to show people what Peeta is all about.

''This is my favourite book of the series, you get to see the whole world. I love it.''

Since starring in the franchise's first movie, 'The Hunger Games', last year Josh admits he has received a lot more female attention, but warned fans he will never be able to accept an invitation to their prom celebrating their graduation from high school, which usually takes place when they are aged 18.

He said: ''Events like this bump up my female following quite a bit. I get quite a few marriage proposals, or asking me to propose to them or asking me to go to prom.

''Now that I'm 21 it'd be really f***ing weird to go to a prom, so I don't think that will be happening.''

Josh, Jennifer and Liam all walked the red carpet at the event alongside fellow co-stars Sam Claflin (Finnick Odair), Jena Malone (Johanna Mason) and Willow Shield (Primrose Everdeen) as well as the film's director Francis Lawrence.

Several stars also turned out for the occasion including Ellie Goulding, Union J, The Wanted's Tom Parker and chat show host Jonathan Ross.
