According to a Billboard report, Blink 182 have already started writing their first post-reunion album, though they are not planning to record until after their comeback tour this summer.

Bassist/vocalist Mark Hoppus explained:

We started writing a few months ago and got well into the writing process, but now we’ve kind of put the recording of the next album on hold and are doing rehearsals for the upcoming tour. We’re still booking the Blink tour for this summer, so we’ll see how that all ends up working out.

Hoppus and bandmates Tom DeLonge and Travis Barker announced their reformation onstage at the 2009 Grammy Awards. They split up in 2005.
