Dianna and Sebastian got hot and heavy earlier this week at New York's rooftop lounge PH-D, according to the New York Post. A source tells the paper that Agron danced all night long and was caught "kissing Sebastian off and on throughout the night." Agron and Stan partied well into the evening along with Jessica Szohr in a booth, the source added.
Agron previously dated 'I Am Number Four' star Alex Pettyfer but the two reportedly split last February.
