According to Dianna Agron, her and guest cast member Chace Crawford's relationship is a combination of "Gossip Girl and Glee just merging together."

During an interview with E! News, the blonde beauty spoke about the 100th episode of "Glee" season 5 in which her character, Quinn Fabray returns with an "über-preppy kid" as her boyfriend.

On Tuesday, March 18th, the original members of the New Directions will reunite in a star-studded, two-part episode.

Crawford who gained fame as an Upper East Sider from the CW's "Gossip Girl" will appear on the Fox series as Biff McIntosh, Quinn's new preppy boyfriend at Yale.

Both the actor and Agron sat down for a behind-the-scenes look of their romance and tried to explain Quinn and Biff's "sugar-coated" relationship.

In the sneak peek Biff says, "I haven't spent that much time around them, but poor people are generally less attractive than rich ones."

Apparently even Chace Crawford isn't a fan of his character as he describes him as an "über-preppy kid" from a North East private school who is both "quite obnoxious" and a "jerk."

To go along with his ego, Quinn failed to mention the whole truth about her past in Lima, Ohio. Dianna Agron explained, "He knows nothing about her real life because she has kind of sugar-coated everything."

However, you can bet your bottom dollar that Santana will attempt to humiliate Quinn in front of Biff, by naming some of her scandalous ways such as setting the purple piano on fire, dyeing her hair pink and of course her Ryan Seacrest tattoo.

"Glee" season 5 two-part 100th episode kicks off on Tuesday at 8 p.m. on Fox.
