Dina Lohan Massacres Mother's Day

And now hell has officially frozen over -- Dina Lohan was celebrated last night as an outstanding mom of the year at a Long Island charity event.

Her ex-husband Michael told us that she was supposed to be at a court-ordered family therapy session just blocks away at the same time, but she chose to attend what looked more like a bachelorette party than an event celebrating celeb moms organized by a group called Mingling Moms.

Of course, the same group also gave Jennifer Lopez an award for being a great mom, and she's only been a mom for three months.
