Who better to guest judge Dancing With the Stars than a Mirror Ball champion?

Season 18 is following two-time pro winner Julianne Hough with Season 9 celeb winner Donny Osmond. The fall 2009 champ will guest judge this Monday, April 14’s Disney Week 5.

Donny isn’t famous for being a Disney star (although, yes, he was in Mulan), but he is a renowned song-and-dance guy, and his positive attitude, high energy, and fun partnership with Kym Johnson helped them win their trophy.

As we’ve already been told, DWTS Season 18 is going to keep going with these guest judges. So far we’ve had Robin Roberts and Julianne, and now Donny. At some point later on, we’ll hear scores and comments from LMFAO’s Redfoo and Ricky Martin.

On Monday, the nine remaining pairs will be dancing to Disney songs from The Lion King, Aladdin, The Little Mermaid, and Frozen, among other popular animated films in arsenal. The couples are all back to their original partners this week, but unfortunately one of the teams will be eliminated at the end of the night. (Unless they pull another mid-show twist.)

So far it looks like Drew Carey and Cheryl Burke have a Quickstep, Meryl Davis and Maksim Chmerkovskiy have the Samba, NeNe Leakes and Tony Dovolani have the Foxtrot, James Maslow and Peta Murgatroyd have Contemporary, Cody Simpson and Witney Carson have Samba, and Charlie White and Sharna Burgess have Jazz.

Are you excited to see Donny back in the ballroom as a guest judge? What Disney routine are you most looking forward to seeing?

DWTS Season 18 airs Mondays at 8 p.m. ET on ABC.
