A source told Perez Hilton that Joshua was the "mastermind" behind this genius piece of matchmaking, and the pair have been on a few dinner dates together in New York, including one special session at Jake's apartment. Ooh!
"Katie says that they have tons in common and Jake has already been to see her in Dead Accountants," said the source.
"Plus she has been over to his apartment in the West Village for dinner."
Katie hasn't been officially linked to anyone since splitting from hubby Tom Cruise last June. Jake's previous celeb squeezes have included Reese Witherspoon and Taylor Swift - two women who have nothing much in common beyond being famous and clean-cut - just like Katie!
Good job, Jake - at least this one won't diss you in a music video if you break up!
