American television personality Kendall Jenner is reportedly having second thoughts about her budding relationship with Formula One ace Lewis Hamilton.

It was previously reported that Kris Jenner is encouraging Kendall to date the 30-year-old, who previously dated American recording artist/actress Nicole Scherzinger.

According to Heat, the 19-year-old Keeping Up With The Kardashians star feels the relationship might damage her modelling career.

"I think Lewis is worried he's not cool enough for Kendall, and she's concerned his career may overshadow her modelling. But Kris is over the moon. She thinks Lewis is the kind of man Kendall needs. She's practically jumping up and down," a source said.

"They first met at the Balmain party at Paris Fashion Week. Lewis had just split up from Nicole [Scherzinger] and clearly fancied Kendall, but she seemed more interested in hanging out with her mates. But Kris was also at the party and was all over Lewis. She practically pushed Kendall into his arms."

"She gave Lewis Kendall's number and told him to call her and ask her on a date. Kendall was mortified, everyone saw her mouthing, 'Mom, stop,' at Kris. But it didn't put Lewis off - he was in contact with Kendall all the time after that," the insider added.

Meanwhile, in February, the former Pussycat Doll broke up with the BBC Sports Personality of the Year after she was reportedly tired of his refusal to commit.

"I'm devastated that it didn't work out. It was the hardest decision we had to make, but we made it together," the former X Factor judge told The Sun at that time.

"I love Lewis and I know he loves me. We wish nothing but happiness and the very best for one another. I'm trying to stay strong in my faith right now," Scherzinger added.
