Just one day after the announcing the cast of season 17 of Dancing with the Stars, former King of Queens star Leah Remini, reality star Jack Osbourne and more were spotted at a Los Angeles dance studio for the first day of rehearsals on Thursday. And despite the sad news released today that wife Lisa suffered a late-term miscarriage last week, Osbourne stayed strong and showed up ready to dance. We can't imagine what he is dealing with but we hope that hitting the floor comes as a distraction to the grieving dad.

Remini was captured entering the studio all decked out wearing a black dress and red heel, while Osbourne made his dad proud by wearing a Black Sabbath cap. The stars look nice and neat now -- but in a few weeks times we bet they will be scruffy in sweats!

Former NFL wide receiver Keyshawn Johnson, comedian Bill Engvall and former Saved by the Bell actress Elizabeth Berkley were also photographed at the studio, readying themselves to get their dance on.

We know DWTS requires hours of strenuous rehearsals -- and we can't wait to see who can really bust a move!

Dancing with Stars twirls onto ABC on Monday, Sept. 16 at 8 p.m.
