In the ultimate expression of moving on from a relationship, Russell Brand, who recently blew up at a heckler for screaming his ex wife's name at one of his comedy shows, has unfollowed Katy Perry on Twitter.

The deletion apparently went down last week. Perry unfollowed Brand almost immediately after their split was announced back in December.

Twitter isn't the only area of her life from which the grape-soda-haired starlet has erased her estranged husband. She also had any and all footage from their relationship removed from her upcoming 'Part of Me' documentary film and unloaded the New York City apartment the couple was to share. She also replaced footage of her and Brand's wedding from her most recent tour with cartoons.

While it was reported that Perry pined for her ex, it doesn't seem to be the case now. She was spotted all over Coachella making out with her new boyfriend, Florence + the Machine guitarist Robert Ackroyd. A source close to the 'Wide Awake' songstress told Us Weekly that Perry and Ackroyd's romance is "still new," telling the mag, "They're having a fabulous time. It's cute puppy love!"
