KATY Perry has fired the ultimate parting shot to husband Russell Brand and unfollowed him on Twitter.

Perry has removed Brand, who goes by the handle Rustyrockets, from the 83 people she follows on the social networking site.

Brand, who filed divorce papers in December, still follows his estranged wife.

Like another recently estranged couple, Demi Moore and Ashton Kutcher, Brand and Perry often used Twitter to flirt and share intimate details of their relationship with their followers.

Brand famously uploaded a picture of his wife without any make-up without her permission. He was forced to take it down by an irate Perry, who is famous for her trademark kooky clothing and overly made-up face.

Perry has remained silent on the impending divorce from her husband of a year.

But while promoting his new show Strangely Uplifting last week, Brand, 36, said he was doing "quite well'' since his high-profile break-up.

Today, Brand stepped out for a Television Critics Association panel to promote his TV show, Strangely Uplifting, which will air on FX in April.

When asked how he was doing, Brand responded, "Quite well, thank you. Are you asking because of recent events?"
