Champagne Papi performed at L.A.'s Kia Forum in Inglewood Wednesday night, dangling the pink prize in front of fans as he crooned in full-blown Toronto patois.

Drake then picked out the lucky female, as the crowd went insane ... and ordered his security to make sure she secured the bag safely. Birkin bags can run well past five figures in retail, so she definitely left with an investment.

We should note, Drake's no stranger to the famous bags, he once admitted he's been collecting them for years, simply to satisfy the woman he eventually calls his wife.

Not to be outdone, Drake's father, Dennis Graham, delivered a gift he had been planning for weeks ... the biggest bra ever and with a note that read, "Dad's wishing 'BIG' things for you, I love you and making sure you're breastfed correctly!!!" 😂😂😂

Drake's fans have been in a bra-throwing competition since we broke the story about Veronica Correia earning a modeling offer after throwing her size 36G bra during the tour in June.

But it looks like Dad's got this one won.
