The One Direction star, who split with Caroline Flack, 32, last month, spent Valentine’s night partying at London’s Groucho Club with Alexa – and it seems they’ve struck up a solid relationship.

‘Sure?’ Harry, 18, Tweeted to the 28-year-old model.

Though Harry and Alexa only chatted and were joined by mutual friend and radio DJ Nick Grimshaw, 27, on their evening out, Xtra Factor host Caroline is said to be upset that her ex spent 14 February with another woman.

‘Caroline’s pals with Nick, so when both Harry and Alexa were guests on his Radio 1 show earlier that evening, she thought the trio would probably end up going out,’ says our source.

‘But obviously Caroline doesn’t like seeing Harry with a model – who would?

‘It’s embarrassing because people will speculate.’
