The cast of “Switched at Birth” reunited in the ballroom to support one of their own Monday night.

During Week 7 of “Dancing With the Stars,” Peta Murgatroyd’s partner, Nyle DiMarco, felt the love as his Freeform family cheered him on from the sidelines. DiMarco, who guest starred on the family drama as Garrett, showed his gratitude by tweeting out a sweet message to Marlee Matlin, Vanessa Marano, Katie Leclerc, Constance Marie and Lea Thompson for attending the live show.

“#SwitchAtBirth in da house,” Constance wrote on Twitter, urging her followers to vote for Nyle, who earned a 29 out of 30 for his elegant foxtrot.

But the “Switched at Birth” cast coming together wasn’t the only special reunion to take place that night. Lea, who competed on the long-running dances series during Season 19 of “Dancing With the Stars,” met up with her shirtless partner Artem Chigvinstev on the set of the hit ABC series. The two finished in sixth place in the series after getting eliminated from the 2014 installment during the quarterfinals.

Marlee also made her return to the dance floor on Monday night — the same one she competed on in 2008 as the show’s first deaf contestant (Nyle is the second to compete on the hip-shaking series). The Oscar-winning actress placed sixth during Season 6 of “Dancing With the Stars” with her partner Fabian Sanchez who was a newcomer to the show.

The “Dancing With the Stars” veterans also partook in “All Access” with host Dominic Bowden in a behind-the-scenes video that shows all the chaos that occurs off of the dance floor. The two cracked jokes together and reminisced about their time on the show.

“Dancing With the Stars” airs Mondays at 8 p.m. EDT on ABC.
