She knows how to keep a man's attention!

Mariah Carey showed a whole lotta boob in a lace bustier for date night with boyfriend Bryan Tanaka, and we have to admit she looks fabulous. The couple hit up Katsuya in Hollywood for some sushi before catching a Laker game, and poor Mimi almost suffered a nip slip while sitting courtside!

The legendary diva was in a great mood all evening, and we think that's because she redeemed herself on Jimmy Kimmel Live! earlier in the day with her first performance since that NYE disaster. The songstress debuted her new song "I Don't" and we think she has another smash hit on her hands.

Things are really looking up for the icon, as she's put her broken engagement to James Packer and her career slip-up firmly behind her. Her new beau is certainly making life a lot sweeter, too!

“Mariah’s very happy with Bryan, and he treats her like a princess. Bryan thinks Mariah is everything, and acts accordingly," a source dished to Hollywood Life. "Nothing is too much for Bryan when it comes to Mariah. He caters to her every whim,” the source added.

It's like she's in a sweet, sweet fantasy!
