Looks like Mariah Carey's backup dancer boy toy Bryan Tanaka is integrating well with the diva's family!

Carey's twins, Moroccan and Monroe, goofed off with the dancer as they touched down at LAX Saturday ahead of the Oscars.

Tanaka pushed Monroe on the luggage trolley as she made faces and laughed. Looks like Bryan's a lot more fun to have around than Mariah's ex fiance James Packer!
