Is newly single Avril Lavigne officially moving on from her ex, Deryck Whibley?
The singer was spotted out with Wilmer Valderrama on Saturday night, surprising onlookers by getting close at L.A. hot spot Wonderland.
Lavigne, who filed for divorce from Whibley last month, arrived with Valderrama at midnight.
