Lucy Hale will guest star on "Baby Daddy"!

Lucy Hale scored a guest star role on Baby Daddy, and she has herself to thank for the job!

At the launch of Baby Daddy season two, Tahj Mowry visited the set of Pretty Little Liars to shoot a series of fun videos as his character Tucker, an aspiring television producer, when Lucy straight-up asked for a guest spot on the show -- and, as ETonline can exclusively confirm, it's now happening!

Lucy will film her role in November and it will air as part of Baby Daddy's third season, coming in 2014.

Meanwhile, there's one episode left in BD's currently-airing second season, which ETonline gave you a first look at the finale -- airing September 4 at 8:30 p.m. -- last week!
