Kellan Lutz may not have anyone special on his arm these days, but that won't stop him from celebrating Nikki Reed's whirlwind engagement.

The 'Twilight Saga' hunk stopped by 'On Air With Ryan Seacrest' Monday to dish about his co-star's new relationship status and touched upon his own love life these days.

"I've never seen Nikki so happy and we really got close throughout all these movies. I'm just so happy for her. It's great to see, especially in Hollywood, that real lovely happiness or marriage."

Reed recently became engaged to 'American Idol' contestant Paul McDonald after only a few months of dating.

"I hope I'm invited!" Lutz said about the upcoming nuptials.

Somehow we don't think Reed will leave her on-screen vampire husband off the guest list. But the real question is: Will Lutz bring on-again, off-again girlfriend Annalynne McCord as his date?
