Mary-Kate Olsen's Taste in Men Is Superbad

Mary-Kate Olsen: Super rich, teeny tiny, known for dating the super rich and influential. Jonah Hill: dorky, chubby, star of stoner comedies, known for knowing Judd Apatow. Obviously these two are dating, right? It's like Brad & Ang, it makes so much sense. The National Enquirer reports (via Celebitchy):

Mary-Kate Olsen is two-timing her boyfriend with a surprising new guy – chubby ìKnocked Upî star Jonah Hill, the Enquirer has learned exclusively. The unlikely couple cozied up to one another at Los Angelesí Chateau Marmont hotel on Aug. 26 – just one night after the stick-thing actress stepped out to a rock concert with steady beau Nate Lowman.

ìIt was a shock to see Mary-Kate together with, of all people, geeky Jonah,î an eyewitness told The Enquirer. ìThey were on a double date with another couple, dining at the hotel around 10 p.m. Mary-Kate and Jonah sat close together and seemed totally into each other. They were both wearing plaid shirts that almost matched. It was the cutest thing.î

ìFrom what I saw at the Chateau Marmont,î said another source, ìMary-Kate had forgotten about Nate and seemed totally enamored of Jonah. And he couldnít keep his eyes off her, either.î

This takes us back to one of our favorite fake celebrity couplings of all time: Nicole Richie and Jeff Goldblum, but with width instead of height.
