Tahj Mowry of “Baby Daddy” is back doing his final “Hey Tucker” segment on the set of “Pretty Little Liars” — who will he run into this week?

None other than Keegan Allen, a.k.a. Toby Cavanaugh, who wonders, “Who are you and why are you in here? … You were stealing things.” But check out what Tucker has on — Tucker is Red Coat! Red Coat is Tucker!

Later, Tucker hits up Keegan for a spot on the show, but Keegan just wants to get him thrown off the set by scary Larry, the security guy. Heh.

“Pretty Little Liars” airs Tuesday nights at 8 p.m. ET/PT and “Baby Daddy” airs Wednesday nights at 8:30 p.m. ET/PT, on ABC Family.
