There was no "I do" ... there was no bended knee ... there was no proposal -- because Drake and Serena Williams are NOT engaged to be married ... this according to a rep for the rapper.
The Internet was buzzing this morning with rumors that Drake had popped the question to the tennis star and she accepted ... but it just ain't true.
Drake's rep tells us, "The rumor is completely untrue."
The two have been spending a lot of time together lately -- and finally busted out the PDA last month ... so, it's probably not entirely out of the question. But for now, pump the brakes on that wedding talk.
