Meanwhile, during an appearance on The Jennifer Hudson Show in October, Thiessen shared her thoughts about turning 50.
"I can't believe it. I actually really cannot believe it. I cannot believe I’m going to be turning 50 very soon," she said. "I feel great. I actually feel more settled than I did in my 40s. Turning 40 was a bigger deal. I’m like, 'Ooh, I’m going to be 50!' I still can't believe it."
The Beverly Hills, 90210 star noted that she's "happy" with all parts of herself, even her wrinkles, noting that she's "earned" them.
"I say earned because I think I've earned them," Thiessen said. "They're from all the tears and laughter -- both! And I’m happy about that."
