We caught up with Leann Rimes as she met up for lunch with friends in Los Angeles today, and she was grinning away like a Cheshire cat.

Leann might be in the middle of a split from hubby, Dean Sheremet, but all she seems to do these days is smile for the cameras.

The fact she was having a fling with actor Eddie Cibrian behind her husband’s back doesn’t matter, clearly.

She looks as happy as ever. Meanwhile, Dean is starting a new life for himself in New York.

Friends say they are still good friends…but we know he must really hate the cheating so-and-so for what she’s put him through. Here’s to the divorce payout Dean!
