In 1984 she starred in Red Dawn alongside Patrick Swazye. The film was about a Soviet occupation of the United States, focused on the political tensions of the time. The film was largely popular and gave them both the acting clout they needed to later rejoin for Dirty Dancing.
Jennifer played the iconic Baby Houseman in the film, and audiences had the time of their lives watching her fall for her dance instructor. She was nominated for a Golden Globe award for her role.
She later played Jennie Bueller, the jealous sister of Ferris Bueller, played by Matthew Broderick in Ferris Bullers Day Off.
Her acting career was a little slower in the 90s but she could still be seen on screens in Friends as Rachel's pal Mindy, and a guest role on House.
She won the US series of Dancing With The Stars in 2010, partnered with professional actor Derek Hough. She has also been a guest judge on Strictly, standing in for regular guest Len Goodman.
Not many people know that she also has a famous family member. Her Father, Joel Grey won Acadamy, Golden Globe, BAFTA and Tony Awards for his role as the Master of Ceremonies in the Musical Cabaret, which starred Liza Minnelli both on Broadway and in the 1972 film version.
He's had other theatre roles in Anything Goes and Wicked, and had a recurring role in Buffy the Vampire Slayer as Doc.
It's been thirty years since Dirty Dancing came out, all the way back in 1987. Jennifer Grey is now 57, and she still looks surprisingly young.
If you're wondering what looks different about her, aside from looking a little older, she had a controversial nose job back in the early 90s. Jennifer has often stated that she regrets getting the procedure, as it completely changed her whole face.
In an interview in 2012, she said: "I went into the operating room a celebrity and came out anonymous. It was the nose job from hell. I'll always be this once-famous actress nobody recognises because of a nose job."
Jennifer is currently married to Actor Clark Gregg, who plays Agent Coulson in the Marvel Cinematic Universe and the TV spin-off Agents of Shield.
They are happily married and have a daughter named Stella.
