Drake did not let 40 sneak up quietly. The rapper threw two lavish New York parties to mark the milestone and handed out gifts most guests will never forget.

A boy band surprise

The first party took place Friday at Casa Cipriani, where Drake reportedly welcomed more than 400 friends and relatives. The headline act was a surprise: the Backstreet Boys.

Clips from the night show Drake shouting "Oh my God" when the group walked out. He grinned, laughed and pointed at the stage before hugging the singers.

Kevin Richardson talked about how the band first got to know Drake. Later the birthday boy joined them on "I Want It That Way" and sang along word for word.

Bags and big money

Guests reportedly went home with Chanel and Hermès handbags. Drake also staged a game show modeled on "Deal or No Deal." Prizes started in the tens of thousands of dollars and topped out at $1 million.

Drake was also filmed speaking about why paying it forward matters to him. He clearly meant it.

Round two at Delilah

A few days later the celebration moved to the Delilah supper club. Drake arrived smiling in a cheetah-print jacket over a white shirt.

Alix Earle came in a black lace look. Travis Scott wore a red and brown outfit. Landon Barker was there with his girlfriend Ashtin Earle, who is Alix's sister.

Adam22 and Lena the Plug, who had separated, showed up together. Jack Harlow kept things low-key in a brown leather jacket.
