Yes! We wanted Lacey Schwimmer back on Dancing With the Stars, and now we're getting both Lacey and Season 14 runner-up Katherine Jenkins, while Cher Lloyd sings her pop anthem "Want You Back.” You want it, you got it! The ladies will perform on the Season 15 All-Stars Week 2 Results Show, which will air Tuesday, October 2 at the normal time, from 9 to 10 p.m.

BUT FIRST, DEFINING DANCES! You're not off the hook from 8 to 9 p.m. Tuesday, because that's when ABC will air the one-hour special "Dancing with the Stars: All-Stars — Defining Dances." During the hour, the judges will select and introduce past routines from the All-Stars’ previous seasons, "ultimately defining the winning attributes that each All-Star demonstrated in these performances." The All-Stars themselves will recount and comment on their mindsets during these selected routines. We've already showcased our favorites of their past routines (plus their best Freestyles) but it will be interesting to hear from the judges and contestants.

RESULTS PERFORMERS: Katherine Jenkins is returning as a special musical guest and she'll perform “Come What May" with Plácido Domingo Their duet will be accompanied by pro dancers Val Chmerkovskiy and Anna Trebunskaya. Also, 19-year-old UK X-Factor star Cher Lloyd will perform “Want You Back.” (Uh!)

MACY’S STARS OF DANCE: We’ll also see the season’s first “Macy’s Stars of Dance” performance, a futuristic standoff featuring some of the world’s most talented dancers battling for dance floor supremacy. The performance will be choreographed by Shannon Mather, spotlighting Blake McGrath, Ian Eastwood and Tyne Stecklein leading their groups in an epic performance.

ICONIC DANCE NIGHT: DWTS will also tease Week 3’s “Iconic Dance Night” with a medley of iconic routines from seasons past, performed by The Troupe as well as talented dancers Anya Garnis, Jaymz Tuaileva, Lacey and Benji Schwimmer. (Isn’t Week 3 usually Personal Story Week? Are we skipping that this season because we already know these stars so well?)

And then, a couple of minutes before 10 p.m., the second couple of the season will be eliminated. Who will it be this time?

Catch a new episode of Dancing With the Stars Season 15: All-Stars on Monday, October 1 at 8 p.m. ET/PT on ABC.
