The ‘Sk8er Boi’ singer Avril Lavigne – who filed for divorce from rocker husband Deryck Whibley last October, a month after they separated – has been enjoying a low-key romance with the 26-year-old reality TV star Brody Jenner for several weeks.
A source said: "They're hooking up but they're keeping it low-key."
Despite trying to keep their romance out of the public eye, the couple recently enjoyed a dinner at Los Angeles restaurant Koi before heading to nearby nightspot Voyeur, where they amazed onlookers with their flirty behaviour.
Another source told E! Online: "You can tell they're into each other and both like to have a good time. They're cute together."
Since splitting from Deryck – who she was married to for three years – Avril, 25, has been romantically linked with actor Wilmer Valderrama and oil heir Brandon Davis, but pals insisted she was just friends with both men.
Brody was most recently dating Playboy playmate Jayde Nicole, but they split in December.
After revealing she and Deryck were to divorce, Avril insisted the pair would remain friends.
She said: "Deryck and I have been together for six-and-a-half years. We have been friends since I was 17, started dating when I was 19, and married when I was 21. I am grateful for our time together, and I am grateful and blessed for our remaining friendship.
"I admire Deryck and have a great amount of respect for him. He is the most amazing person I know, and I love him with all my heart. Deryck and I are separating and moving forward on a positive note."
