Karl-Anthony Towns got a dope surprise for his 26th birthday -- a party and a $13,000 custom Louis Vuitton bag from his girlfriend, Jordyn Woods!!
The Timberwolves center went out to celebrate his cake day after his game against the Suns on Monday ... but was not aware that a surprise bash was waiting for him.
You can see the 6'11" All-Star and Woods walk into what appears to be a restaurant, when a big crowd screamed "SURPRISE" -- and KAT was in complete shock!!
The fun didn't stop there ... KAT, Woods, friends and fam took the party back home as you can see Towns in his PJs and flops enjoying his birthday cake.
