Tia Mowry, the star of Sister, Sister, and her husband, actor Cory Hardrict, 31, are expecting their first child in July, a source tells PEOPLE.
"This is something that they've wanted for a long time and they're thrilled," the source says.
The parents-to-be were married in 2008 in an outdoor ceremony in Santa Barbara, Calif. "You can tell they're really in love," wedding planner Robyn Goldberg told PEOPLE at the time.
Mowry, 32, who can currently be seen on BET's The Game, starred in the 1990s sitcom Sister, Sister with her identical twin, Tamera Mowry.
According to reports, her pregnancy will be documented on a TV show on the Style Network later this year.
