Couple Alert: Amanda Bynes and Doug Reinhardt

The Hills might add an actual actress to their repertoire if things go well for Brody Jenner’s baseball-playing best friend Doug Reinhardt.

It seems the 23-year-old stud, who once courted Lauren Conrad, Stephanie Pratt and Holly Montag, has taken an interest in Hairspray star Amanda Bynes.

As Celebuzz previously reported, the pair were spotted canoodling last week at West Hollywood lounge Apple.

Now, sources say the couple showed to the scene of the crime once more, “hand in hand, sitting closely together at the owner Alison Melnick’s table.”

Hand in hand, indeed!  The eyewitness also reveals that Reinhardt and the 22-year-old thesp were “very cute and flirty, whispering in each other’s ears the whole night.”

Bynes has been linked to the likes of once-costar Channing Tatum and even millionaire Family Guy creator Seth MacFarlane, 13 years her senior.

Perhaps love was everywhere.  Paris Hilton also turned up at Apple with some gals from her MTV show My New BFF. She partied peacefully alongside ex-beau Josh Henderson.
