Parrish posted a Instagram photo of herself drinking coffee on Sunday along with the caption, Can't feel my legs. How am I gonna get through rehearsal today? The answer is always COFFEE". The actress is preparing for the first week of competition with her assigned partner, Val Chmerkovskiy.

Chmerkovskiy recently joined Parrish in an Us Weekly video interview, discussing how they feel as they prepare for the Monday, Sept. 15 premiere of the season.

"We feel pretty confident," Parrish said. "We're a good team, and I got a great coach. I like the way he teaches. Sometimes I'll get frustrated when I feel like I'm a little bit overwhelmed, but that's just me wanting to get things right."

Chmerkovskiy quipped that when he goes home after rehearsal he will "break down in private."

As for Parrish's fellow celebrity competitors, she said that comedian Tommy Chong, 76, has "some moves," while Chmerkovskiy added that he has "the illest hip action I've ever seen, for sure." Older celebrities do not traditionally do very well on Dancing With the Stars, but anything is possible.

In the mean time, the dancing couple are now calling themselves "Team Janelskiy," a portmanteau of Parrish's first name and Chmerkovskiy's last name.

Dancing With the Stars Season 19 is set to premiere Monday, Sept. 15 at 8 p.m. ET/PT on ABC.
