"Take Care" hit maker Drake and Serena Williams have fuelled the romance rumors once again as the pair was spotted kissing at a Cincinnati restaurant on Aug. 23, Sunday, just hours after she won the Women's Tennis Association tournament.

Earlier, the rapper was spotted cheering for his lady at the WTA tournament. Later, the pair reportedly hit the uber-fancy Sotto restaurant in downtown for some Italian food where the two allegedly asked for a private room in the back of the eatery.

Later, the rumored couple was joined by six other unidentified people and the group appeared to have a blasting time. However, Drake and Williams seem to remain oblivious as the two "couldn't keep their hands and lips off of each other," an onlooker told TMZ.

While the 33-year-old Tennis star showed off her toned arms and ample cleavage in a white tank top with her voluminous hair tied back in a pony tail, the rapper was seen in a grey hoodie and black jacket with dark coloured jeans, Daily Mail reported.

The recent spotting of Drake and Williams has once again set the tongues wagging that the two are dating each other. Back in July 2011, the two were spotted kissing in the clubhouse after her victory against Victoria Azarenka in the Wimbledon quarter finals, after which it was rumored that the tennis star is in a romantic relationsip with the 28-year-old rapper.

Although the couple has always denied the rumors with Williams even laughing it off during an interview in 2011, it is almost confirmed that the two are involved in an on-and-off relationship. Drake is also said to have rapped about her in his 2013 hit track, "Worst Behaviour."
