Simon Cowell has a crush on make-up artist Francesca Neill.

The mogul is attracted to the former model, who works on his TV show 'Britain's Got Talent' as assistant to judge Alesha Dixon.

Although Simon - who is believed to have split from fiancee Mezghan Hussainy earlier this year - admits he is smitten with Francesca, he hasn't been able to pluck up the courage to ask her on a date yet.

He said: ''We have the new, cutest make-up artist. But I just can't talk to her, I'm kind of tongue-tied.''

Simon, 52, was asked by 'Britain's Got More Talent' host Stephen Mulhern if he wanted him to ask Francesca out on his behalf, but replied: ''No, that would make it awkward.''

Simon was then teased by his fellow judge David Walliams, who told him she had a boyfriend, adding: ''I hear he's a cagefighter.''

Francesca - who dated singer Craig David in 2007 - is a new addition to the 'Britain's Got Talent' team, and followed Alesha from her former show 'Strictly Come Dancing'.

A source told the Daily Mirror newspaper: ''She has only met Simon a few times and he hardly spoke to her. Now she knows it's because he really fancies her.''

The 27-year-old model's friends took to twitter after hearing Simon discuss her on the show, with one saying: ''Simon totes wants to get in your panties (sic)!!!''

She responded: ''hahahahaha (sic).''
