Nicole recently chatted about one of her tattoo regrets.

“I have a few tattoos, but I haven’t gotten a new one since I was 21,” Nicole shared to Into the Gloss. “I was a 19-year-old idiot when I got this tattoo on the back of my neck.”

FYI: Cameron is wearing Strom Brand jeans while leaving the gym.
