On tonight's episode of YOUNGER, titled "Fever Pitch," Kelsey (Hilary Duff) escapes from the Big Apple with her publicist pal, Lauren (Molly Bernard), for a spontaneous getaway with Liza's ex, Josh (Nico Tortorella), tagging along. However Kelsey fails to mention that detail to her co-worker and BFF! Check out the ET's exclusive sneak peek below!

YOUNGER follows 40-year old Liza (Sutton Foster), a suddenly single mother who tries to get back into the working world, only to find it's nearly impossible to start at the bottom at her age. When a chance encounter with the sexy Josh (Nico Tortorella), a young tattoo artist, convinces her she looks younger than she is, Liza tries to pass herself off as 26 - with the help of a makeover, courtesy of her best friend Maggie (Debi Mazar).

Armed with new confidence, she lands a job as an assistant to the temperamental Diana (Miriam Shor) and teams up with her new co-worker and 20-something Kelsey (Hilary Duff) to make it in the career of her dreams. Now she just has to make sure no one discovers her secret.
