Xtra Factor host Caroline Flack has reportedly been getting jealous after ex One Direction boyfriend Harry Styles was spotted flirting with Alexa Chung.
Harry and Alexa were photographed last week sharing a cab home together on Valentine ’s Day, following an on-air party with Radio 1 DJ Nick Grimshaw.
"Caroline was so angry about Alexa and Harry hanging out," one spy tells Star magazine this week. "They might not be together any more, but there are feelings there and they're talking a lot.
"A reunion is still definitely on the cards, so Caroline wants Alexa to stay clear."
At 28, model and telly presenter Alexa is four years younger than Caroline, and it's worrying her!
"She was envious to see Harry out with someone as gorgeous as Alexa, and hearing them flirting on the radio was really upsetting," the source continues.
They added: "It might have been innocent but no one wants to hear their ex chatting with another woman like that. It was really hard for her."
Harry and Caroline, 32, ended their three month fling turned relationship last month, but sources close to the couple have insisted they've remained almost inseparable since.
