Janet Jackson Opens Up About Getting Older in Rare Interview: 'I Do Hope I Age Gracefully' Last month, another of Philipps' Instagram posts captured the attention of her mother, leading to a hilarious text exchange between the two. The Cougar Town actress shared a "thirst trap" photo of herself relaxing in a pool, writing, "This is 100 percent the hottest self timer pic I've ever taken," noting "there's no lame comment where I try to buy back what this is." Busy Philipps/Instagram Busy Philipps Had a Scare After a Mammogram When a Cyst 'Looked a Little Weird' Later that day, Philipps returned to Instagram, revealing that her mom Barbara Philipps expressed some concerns. "This is what I get for posting that thirst trap. This text from my mom," she wrote alongside a screenshot of their text exchange, in which Barbara said she was worried after a fan pointed out a piece of skin on the right side of her daughter's body. "Biz-Someone commented on your insta pic about your right underarm looking swollen and it does," the text read. "Please take a look and get to a Dr. if it is." "Stop. It's fat. Seriously stop it," the actress wrote back.

Barbara's concern comes just months after Philipps opened up about a recent health scare. In an interview with Health magazine for its June cover, Philipps revealed that doctors recently found a cyst that "looked a little weird" when she went in for a mammogram. A biopsy on the cyst ultimately returned clean. "My feeling is, there's no reason to get upset until they tell you to because it's a waste of energy — you can't change the results," Philipps said at the time. "When those scary thoughts creep in, I say, 'I see you, thoughts. I am going to put you away in this little cabinet.' "
