Heather started shooting an episode of the current season of Young & Hungry, which she revealed by posting a pic of the script on Instagram earlier this week.
There aren't a lot of details available about her cameo just yet, but we know that she'll be playing a character named Natasha Cook Campbell, and her "co-star" is a cute, pampered pup.
While on set, Heather also caught up with Young & Hungry stars Emily Osment, who plays food blogger-turned-personal chef Gabi, and Jonathan Sadowski, who plays wealthy tech entrepreneur Josh in the show.
Heather also remembered her time starring alongside Jenny McCarthy on her '90s sitcom Jenny with an adorable photo of the pair on Instagram in honor of Throwback Thursday this week. Some of Heather's other past roles include stints in Hot in Cleveland and Sequestered.
