Did Justin Bieber's mom Pattie Mallette and Chris Harrison go on a date?

Did Justin Bieber's mom Pattie Mallette hit the town Tuesday night (Oct. 2) with "Bachelor" franchise show host Chris Harrison?

Pattie tweets the above photo along with, "Had a great night w @chrisbharrison! Thanks @ryanseacrest for setting it up."

And Harrison tweets, "Huge thanks to @justinbieber @pattiemallette for an incredible night. Huge cool dad pts! Great show!"

Seacrest adds, "Does he get a rose? RT @pattiemallette: Had a great night w @chrisbharrison! Thanks @ryanseacrest for setting it up."

Hmm. Well, maybe not so much a "date" as Harrison got hooked up to take his kids to Bieber's Los Angeles-area concert? But Harrison is newly single -- and we think he and Pattie actually look pretty adorable together.
