Happy Mother's Day, Mariah!

Of course the best gift Mariah received was spending time with her twins Moroccan and Monroe, but was the second-best gift getting to spend time with their dad Nick Cannon?

The family of four hit up Nobu Malibu for their Mom's Day celebration and Nick and Mariah looked as close as ever -- he had his hand on the small of her back as their left the oceanside hot spot; they two looked lovingly into each other's eyes. The kids looked happy as clams to have their two parents together -- all in all, a great day for the foursome.

But was it just for Mother's Day or could Mariah and Nick be making moves to permanently repair their family? Recent reports claim the two are getting closer after Carey's breakup with backup dancer Bryan Tanaka a month ago while other rumors say the two are just very successful at co-parenting.

If our photos from Sunday are any indication, we think it looks like Nick and Mariah maybe on the road to recovering their romance!
