Kimberly Stewart likes to keep her men on a roll.
In her latest romantic fling, Kim has been seen passionately kissing rocker Caleb Followill.
The 27-year-old was reportedly all over the Kings of Leon frontman at London's Kabaret club.
A source told Britain's Daily Mirror newspaper: "They were getting stuck into drinks on a private table and Kim was all over him like a rash."
Kimberly and Caleb continued canoodling after they left the club, going back to fellow reveler Natalie Imbruglia's suite at The Dorchester hotel.
The source added: "Once they got back to the suite, the alcohol came out again. But all Kimberly and Caleb were interested was one another and spent most of the night making out to everyone's embarrassment.
"Natalie knows all the Kings of Leon really well and she was delighted when they hit it off."
Kimberly - the daughter of Rod Stewart - is in London to shoot the new campaign for fashion line Pinko.
Caleb, 25 - whose band is currently topping the U.K. album charts with the album "Because Of The Times" - will have to be on his best behavior if he continues to romance Kimberly.
Last year, British comedian Russell Brand was publicly berated by Rod for saying he had slept with Kimberly.
