PopUps: Is Andy Cohen Dating a Harvard Student?

The rumor mill is in full swing this week and tabloid reports are suggesting Bravo's Andy Cohen is dating a 28-year-old Harvard PhD student.

According to the Daily Mail, Cohen took a vacation on billionaire Barry Diller's yacht last week - the second time in three months - and was accompanied by Clifton Dassuncao both times. The newspaper reports Dassuncao is an Environmental Science and Engineer student at Harvard University.

Dassuncao can be seen in a photo posted to Instagram by The Palms owner Bruce Bozzi, who is best friends with Cohen, 47.

"Hello Thursday! Yesterday's afternoon adventure!!!" Bozzi captioned the snap. Bozzi is in the image alongside his partner Bryan Lourd, Diller and wife Diane von Furstenberg, producer Jason Blum and his wife Lauren. Cohen and Dassuncao are also in the image.

The Daily Mail reports Dassuncao posted selfies on Diller's yacht last December. In one pic, he used the hashtag "#moneybusiness." Cohen reportedly commented on the Instagram post, writing, "Monkey business is right."

The newspaper points out Dassuncao, who's Instagram account is private, first posted a pic with Cohen in July after seeing him on Cohen's Bravo show "Watch What Happens Live." A week later, the student posted an Instagram snap of his summer reading list, which included "The Andy Cohen Diaries." Cohen reportedly liked the post. The Daily Mail also reports Dassuncao is one of the 260 Cohen follows on Instagram.

Dassuncao has worked for the CDC, the U.S. Geological Survey and has done research at Harvard, according to his LinkedIn. He grew up in Queens, New York and attended the Massachusetts Institute of Technology before receiving his Master's Degree from Harvard.

The Daily Mail notes Cohen has been very private when it comes to his sex life, though he did confirm he hooked up with Lance Bass. Cohen lives in the West Village in New York City.
