Yet another ex is in Johnny Depp's corner!
The letter, dated Friday but only revealed now says in part:
He's single and totes ready to mingle???
Robert Pattinson was spotted hitting up L.A. club No Vacancy Tuesday night, with his best guy friends in tow!
But was he on the prowl for a new lady love?!
While he appeared to be happy, R-Patz chilled with pals on the balcony until about 1 a.m.!
