Serena Williams and Drake spotted 'making out' during date night

DRAKE AGAIN!!! Here it is ... proof Drake
and Serena Williams are officially a thing --
making out at a fancy Cincinnati restaurant
Sunday night ... TMZ reported. Hours after
Serena dominated and won the WTA
tournament in Cinci -- with Drake in the crowd
-- the two hit up the uber-fancy Sotto restaurant
in downtown for some hoity-toity Italian food
(the porterhouse is $85). The two had a private
room in the back of the eatery -- where they
couldn't keep their hands and lips off of each
other ... while several patrons watched.
People inside the restaurant tell us the two were joined by 6 other people ...and at one point ordered a round of tequila shots for the table. There have been rumors about the two hookin' up for months -- ever since Drake was spotted cheering for Serena at Wimbledon -- but now the pics confirm it ... it's game on.
