New couple alert! Rumors are flying around Hollywood that 'Mad Men' actress January Jones and 'Saturday Night Live' cast member Jason Sudeikis are dating. The pair both attended the ESPY awards on Wednesday night and apparently weren't too shy about PDA, Just Jared.com reports.

"January and Jason were making out the entire time in front of friends," a partygoer revealed. "They seemed really happy and comfortable with each other."

Jones has also been making regular appearances on the set of Sudeikis' new film, 'Horrible Bosses.' A source tells JustJared.com, "They were pretty flirty together!"

The couple met when Jones, 32, hosted 'SNL' last November. They were featured in several sketches together including a 'Rear Window' parody. Sadly, her overall hosting skills were generally panned.
