Avril Lavigne Makes Out With Brody Jenner, Tramples Deryck Whibley’s Heart (PHOTOS)

Oh, dear; it appears that Avril Lavigne is determined to rub it in ex-husband Deryck Whibley’s face—by brazenly sucking face with her new beau, Brody Jenner, in front of God, the paparazzi and everyone.

The “Sk8er Boi” singer—who split with Sum 41 singer Whibley in September after three years of marriage—was spotted tooling around—in every sense of the phrase—Hollywood in Jenner’s 1968 Dodge Charger on Thursday, and because no woman can resist a reality-TV stud in a classic muscle car, Lavigne planted a passionate wet one on the stubbly-chinned Hills heartthrob.

Way to give an ex the old kiss-off, Avril—unless this is part of some diabolical plot to pump up interest in The Hills’ final season.
