The "Donnie Loves Jenny" star traded in her signature blonde tresses for a neon pink hue, debuting her wild new look on Twitter on Tuesday.
"Thank you to my amazing hair & makeup team this morning! @JuliusMichael & @mspriscillanyc," she captioned the pic of her mane makeup, crediting her glam squad for their skills.
The 42-year-old bombshell talked about her newly-dyed locks during an appearance on "Today."
"This morning I woke up and said, 'I'm feeling pink," she told Hoda Kotb and Kathie Lee Gifford. "This is something I've wanted to do forever. I've always been told by networks and bosses, 'Don't do it ...' So, I figured, I'm still at the age when I can get away with it."
So, what does hubby Donnie Wahlberg think of her new 'do?
"I showed him this morning quickly," she revealed. "And he said, 'You look beautiful.'"
McCarthy continued to gush about her husband, admitting, "We are very much in love."
"We really are addicted to each other," she added. "I think about him all day long, still. When he's on the road, and I'm back here, we Facetime sleep ... all night. He's on the pillow, I sleep and hear him snore. We sleep that way."
Whatever works, right?!
