Olly Murs has spoken about his close friendship with his Xtra Factor co-host Caroline Flack, saying they are "BFFs".

The singer revealed that he "cares a lot" for Flack, and was there for her following her split from One Direction star Harry Styles.

He told New magazine: "Me and Caroline are BFFs and we just have a laugh.

"We just get on really, really well and I'm always there for her if she needs me. If she ever has any problems or if she's upset."

Murs also addressed the negative reaction Flack received after dating someone 15 years younger than her, saying: "Obviously, there have been stories about her she hasn't liked and she can always confide in me. I care a lot about her.

"She's a lovely girl and sometimes you can't help who you fall for. It was not a nice time for her, but I think she handled it really well.

"It was a tough time for her, but I'm friends with Harry as well and I didn't want to get involved in it too much. Caroline spoke to me about it a couple of times, but it's her private life and her affair to deal with."
