G Hugh Grant serious, 01/04Hugh GrantInviting your ex to your wedding is a dodgy thing to do.

You risk upsetting your current beau...

... And there's always the chance your ex might object to your nuptials, half-way through the ceremony.

So is that the reason Hugh Grant isn't going to Liz Hurley and Arun Nayar's wedding?

He told Hello! magazine that he's been left off the guest list, despite them supposedly being bessie mates:

"That's not surprising," he said.

"I don't think many people invite their ex when they get married, so I'm not at all bitter, and there's no bad feeling or weirdness, we're just not invited."

Hugh's new lady Jemima Khan must be pleased... it's thought her and Liz aren't so matey.
