Millie Mackintosh has said that she enjoys accompanying Professor Green to his festival dates.

The Made In Chelsea star recently returned from Ibiza, where her rapper boyfriend (whose real name is Stephen Manderson) performed, and is set to jet off to Spain for his Mallorca Rocks concert on July 17. He will also play a number of UK gigs including the V Festival.

"It's great, you know. I'm getting used to the travelling [and] living out of a suitcase. It's going to be a really exciting summer," she said at the Nature Valley Games 2012.

While Millie - who participated in the Games alongside ex-The Only Way Is Essex's Amy Childs and former Olympians Roger Black and Jamie Baulch - refused to comment on whether she would accompany him to the US, where he plans to start recording his third album, she hinted that there would be a fourth series of ITV2's Made In Chelsea.

"Who knows? It's amazing that we've done a third series. We didn't know if it would make it past the first episode but I think there's definitely a demand for more so there'll be more filming coming up soon," she said.

The 22-year-old, who was ranked in fourth place, admitted she doesn't have time to work out regularly.

"I like to keep healthy. I could be fitter but I am very busy and I find it very hard to fit in the amount of time that I'd like," she said.

"I do like riding and country sports - they're more my thing. I don't like working out in a gym."
