The worst kept secret of Dancing With the Stars Season 16 is finally out: Bachelor Sean Lowe is indeed joining the Dancing With the Stars 2013 season, along with pro dancer Peta Murgatroyd.

The news was confirmed on Good Morning America on March 12, the day after The Bachelor finale, where Sean proposed to Catherine Giudici.

Peta, who is back to blonde, said they’ve been keeping this DWTS partnership a secret for a while now. But Sean will “absolutely” be ready before next Monday’s Season 16 premiere.

Sean said he signed up for DWTS so when he and Catherine have their “big day” — they’re already planning a TV wedding on ABC — he can make her proud. 

What do you think of this official news? Are you excited to see Sean dance (with Catherine presumably visiting him in rehearsals and cheering in the audience) or do you think he should be spending this time with his fiancee before their wedding? DWTS tapes in L.A., so this is why Sean and Catherine hedged so much on the After the Final Rose special about Catherine moving to his home city of Dallas.
