Reigning Formula One champion Lewis Hamilton, who has been romantically linked with Kendall Jenner, is reportedly worried he isn't "cool enough" for the reality TV star.
Kendall's mother and manager Kris Jenner is, however, "over the moon" with the link-up.
"I think Lewis is worried he isn't cool enough for Kendall and she's concerned his career may overshadow her modelling. But Kris (Jenner) is over the moon. She thinks Lewis is the kind of man Kendall needs. She's practically jumping up and down," a source told Heat magazine.
Lewis and Kendall first met at a Balmain party during Paris Fashion Week in March and the brunette beauty was left "mortified" by her mother's matchmaking.
"Lewis clearly fancied Kendall but she seemed more interested in hanging out with her friends. 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 source added.
