“Matt Damon made it after all!” she captioned the cute picture, which shows a cake shaped like Mars and an astronaut figurine poised on top with a photo of Damon’s face on it.
In May, the “Just Give Me a Reason” singer, 36, revealed that she got in trouble with Willow, who just turned 5, for telling the press about the little girl's crush on the Martian actor.
“She’s already upset with me because there's a new game we play called ‘Ask Siri’ — which, she just found out last week there’s a Siri — and I said, ‘Siri, Willow, Matt Damon,’ and all this stuff came up,” she told Entertainment Tonight on May 3. “[Willow’s] like, ‘How do they know?’ She got mad at me! I was like, ‘Oh, my God, I need to keep my mouth shut. Sorry!’”
Pink, who shares Willow with her husband, BMX pro Carey Hart, first revealed Willow’s celebrity crush during an interview on the Kyle and Jackie O radio show at the end of April.
“She loves [The Martian]. I love it. I thought it was great, but I don’t love it the way she loves it,” the Grammy-winning singer told the Australian radio hosts. “She asked me if Matt Damon can come to [her birthday party]. I think she has a crush.”
The pop singer joked that Damon, 45, is the first person who Willow thinks about when she wakes up in the morning.
"She wakes up and rolls over and goes, 'Matt Damon,'" Pink said, laughing. "I'm like, 'I know.' … I'm thinking I'll get her a Matt Damon poster [for her birthday]. I've never talked about Matt Damon this much in my life! She made me Google Matt Damon dolls. That was disturbing. Do that sometime, they're very disturbing."
