Washington: ‘Mad Men’ star January Jones has apparently ended her relationship with SNL star Jason Sudeikis.

The couple was first linked in July after they were spotted making out at an ESPY after party,

But a source revealed this summer that Sudeikis`` pals weren`t thrilled with the match-up.

"His friends don`t understand why he`s dating her. They call her an airhead behind his back. She doesn`t get their jokes. They`ve only known him to date smart, funny women," quoted the source as saying.

Jones although seem less affected by the split as she flaunted her assets at the Golden Globes in a cleavage-baring Versace.

The actress, who recently posed nude for the fashion company, spoke about her experience at HBO``s after party.

"I loved it. And, as a matter of fact, I`m wearing Versace right now!" she said.
