A source told British magazine Grazia, "Justin and Jennifer are so happy right now - they don't want any bad feeling in any aspect of their lives by the time they tie the knot."
"Justin knows that Jen and Brad talk occasionally and he likes the actor [the pair have met a few times]. Obviously, this means inviting Angelina too. Jennifer was taken aback, as she really didn't think Justin would want her ex-husband there, but she loves the fact he's so OK about it."
