The Mills family finally has a father.

Rob Estes will join the cast of The CW’s 90210 spinoff as Harry Mills, a father who moves his family from Kansas to Beverly Hills, according to a statement released by the studio and network.

Harry is the principal of West Beverly High School, his alma mater, where his two children played by Shenae Grimes and Tristan Wilds will attend.

Estes is probably most famous for playing Kyle McBride in the popular ’90s nightime soap, Melrose Place.

His announcement rounds out the 10-member cast, but viewers can expect guest appearances from Jennie Garth, who will reprise her role as Kelly Taylor.

Taylor who is a guidance counselor at West Bev High is the first alum to join the spinoff from the original cast. –Elaine Aradillas
