We just received official word from Rupert Grint's publicist that the actor will definitely be attending the premiere for his film Cherrybomb in Berlin this weekend. Tickets went on sale online on Monday for the Feb. 10 show and have completely sold out.

According to the festival website, tickets for the Feb. 8 screening (which is the actual premiere) are supposed to go on sale today, while tickets for the Feb. 9 screening will go on sale tomorrow. You can purchase tickets here.

Rupert's publicist also told us that it is 'unlikely' that Rupert will attend the Cherrybomb screening at the Dublin film festival on Feb. 20. This comes as no surprise since he will be filming Harry Potter and the Deathly Hallows at that time.

UPDATE: RupertGrint.net is reporting that tickets for the Cherrybomb premiere and the February 15th showing, have now sold out!
