The middle seat at the "Dancing With the Stars" judges's panel is getting another shake-up. Julianne Hough, fresh off her successful run as Sandy in "Grease: Live," announced that she's not returning to judge the DWTS Spring 2016 season, which premieres March 21 on ABC.

Instead, head judge Len Goodman will return to his seat between Carrie Ann Inaba and Bruno Tonioli. (Woo hoo!) It's not unexpected to see Len return -- he loves DWTS, he just hates judging both "Strictly Come Dancing" and DWTS in the fall, since it requires commuting back and forth from London to L.A. every week. "Strictly" doesn't air in the spring, so he can stay in L.A. for the duration.

But what does this mean for Julianne? It sounds like her acting/performing career is heating up, and she may focus on that for a while. Here's what she and DWTS showrunner Rob Wade told People:

Julianne Hough: "I will miss being on the panel for Season 22, but have a lot of exciting stuff coming that I look forward to sharing. The pro dancers, producers and crew at DWTS will always be my family."

Rob Wade: "Julianne will always be a part of the Dancing with the Stars family and we hope to see her back in the ballroom in the future," producer Rob Wade tells PEOPLE.

Julianne: "I promise it's not the last you'll see of me in the ballroom."

But will she ever return as a judge? Julianne has left DWTS before -- she won Season 4 and Season 5 as a pro dancer, then quit after Season 8. She returned as a guest performer for a few seasons, and later as a guest judge. She joined the official judging panel in Season 19.

So it seems likely that we'll see her back in the ballroom to dance, and maybe sing, but will she return this fall to judge Season 23, if Len Goodman skips his London-L.A. commute again? Or maybe we won't get a Season 23 at all...
