Two of Hollywood's hottest franchises are merging -- sort of. Bonnie Wright and Jamie Campbell Bower -- who respectively star in the Harry Potter and Twilight films -- reportedly are engaged.

The Daily Mail claims that 21-year-old Bower, who played the vampire Caius in New Moon, popped the question to 19-year-old Wright, who plays Ron Weasley's sister Ginny in the Potter movies.

The two will appear together in the upcoming Harry Potter and the Deathly Hallows, in which Bower portrays Gellert Grindelwald.

Wright confirmed to People magazine in February that the pair had been dating for about six months. She said, "It's not like we kept it a secret intentionally, but we didn't go around telling everyone either. We met at a party, and we just really clicked straight away. He's a great guy, and we just enjoy spending time together."
