The Take Me Out: The Gossip duo sparked speculation after they arrived together at the ITV2 party held at the W London hotel.
However, talking to Digital Spy last week, 29-year-old Hardman said that although Wright has a good body, she thinks of him like "a younger brother".
Last night, she tweeted: "I'm drunk. On a Tuesday. I'm in pain already."
They were joined by the current TOWIE crew Billie Faiers, Jessica Wright, Mario Falcone and Lucy Mecklenburgh.
Also on the ITV guest list were Emma Willis, Stephen Mulhern, Caroline Flack and Leigh Francis.
Singer Peter Andre attended the dinner but arrived without his girlfriend.
