Heidi Montag, Spencer Pratt Celebrate Mother's Day

Celebrity gossip fans know that a holiday just isn't a holiday without cheesy, staged pics of Heidi Montag and Spencer Pratt. The gruesome reality twosome never misses an opportunity to spend time with family ... while raking in the cash of course.

Heidi and Spencer Pratt took his Nana - who fans of The Hills surely remember from last season - out for lunch at Spago for Mother's Day in Beverly Hills Sunday.

Spencer, his grandma, Heidi and her giant bag pose for a photo.

Conspicuously missing on this touching Mother's Day outing? Stephanie Pratt, whose absence Spencer surely noted at length, as well as their actual parents.

Of course, it's amazing Heidi Montag convinced them to attend her wedding to the blonde bearded one, so they've likely had their Spencer fix for the decade.
