Lavigne and Jenner were at it again just last night at Les Deux nightclub in Hollywood. "Avril kept grabbing Brody, hugging him and whispering in his ear," our spy tells us. "She was dancing very provocatively and kept shoving cigarettes in her mouth."
Another eyewitness adds: "Brody and Avril were making out all night and couldn't keep their hands off each other."
And while Lavigne is said to be flip-flopping between Jenner and her estranged rocker hubby, we've also learned...
Whibley had a grand ole time when he recently celebrated his 30th birthday in Las Vegas at Tao followed by more fun a couple of nights later at the Playboy Mansion in L.A. "He was totally making out with a brunette no one had ever seen before," a Mansion eyewitness tells us.
Even so, Lavigne and Whibley aren't completely dunzo. Paparazzi video surfaced from Sunday night showing the duo leaving West Hollywood's Crown Bar...together!
"Avril is single," a Lavigne pal says. "She's having fun"
