Jennifer Aniston can’t believe how lucky she is to have recorded the song “Push and Pull” from her new film Dumplin’ with Dolly Parton. The actress recently spoke about it to Entertainment Tonight. 

“[I was so nervous] but I sang through it and then got my voice,” Jennifer said. “I literally couldn’t have a squeak come out, and then when we finished, I remembered, I just burst into tears.” 

“She did get emotional after she was done,” Dolly added, calling Jennifer a “real pro” in the booth.

“It was terrifying and fun and all of it… it was great,” Jennifer recalled. “[I was] fearless, yes, or fearful, depending on how you look at it. But I had Dolly and Linda Perry there, who were just patient and wonderful.”

In Dumplin’, Jennifer plays a former beauty queen whose plus-size teenage daughter, nicknamed “Dumplin'” (played by Danielle Macdonald), signs up for her mom’s pageant in protest.
