Teddi Mellencamp's hair is getting longer each day. Mellencamp, 44, showed her growth - both inside and out - amid her ongoing cancer battle in a message shared via Instagram on Monday, September 22. The Real Housewives of Beverly Hills star brushed her mane to one side of her head in a newly shared selfie, embracing her brunette roots and platinum blonde ends. The TV personality went makeup-free in the photo, showing off her clear and hydrated skin. She accessorized with a mix of dainty hoop and stud earrings, tying her look together with a brown hoodie.
