Catherine Zeta-Jones gets star struck by Bono.
Even though the Welsh beauty can remember the 'One' singer and his band U2 from before they got famous in the 80s, she still gets excited by his stardom when they see one another.
She said: "I remember seeing U2 when they were just an Irish band before they made it big and it blows my mind that Bono says, 'Hi Catherine, how are you doing?' I'm like, 'Oh my God, it's Bono!'"
Catherine, 42, has children Dylan, 11, and Carys, seven, with her husband, Michael Douglas, and admits she has to pull herself together when she takes them to Bono's house at Halloween.
She added: "I can clearly remember going trick or treating with my kids to Bono's house. I had to be really grown up and get it together."
The 'Rock of Ages' actress embarked on a pop career of her own in the early 90s, releasing several singles but she has no plans to resurrect her pop career.
She added to Britain's OK! magazine: "It'll go down historically and there's going to be a movie made out of that era too. It was a world that was just fascinating to me but I definitely prefer acting."
