Jessie J fell for her rumoured new boyfriend when he was giving her tips on how to look good on TV.

The British singer can currently be seen on the UK version of The Voice, where she is acting as a judge.

She reportedly felt worried about how she would be compared to the other members of the panel, Sir Tom Jones, Danny O'Donoghue and will.i.am so asked British rapper Tinie Tempah for advice. The two are now rumoured to be in the first flushes of love.

"I thinks she had a shaky first couple of days when she recorded the auditions last month," a source told Look magazine.

"So he talked her through a few pointers to get her on-screen performance up to scratch. Then he invited her over to his place to hang out and that's clearly when the sparks between them started to fly!"

The pair have been spending increased amounts of time together but have eschewed showbiz hangouts for more down-to-earth pursuits. According to insiders they have been enjoying romantic strolls and meeting for drinks in cafes as they try to work out how compatible they are.
