AceShowbiz - Actress Emma Stone has Sir Paul McCartney to thank for making her first and last tattoo a one-of-a-kind experience. The Beatles legend drew the artwork she's having inked to celebrate her mother's recent triumph over breast cancer.

The 21 year old met McCartney while filming "Zombieland" with actor Woody Harrelson in 2009 and struck up an unlikely friendship with the rock icon after spending a day at his house. She says, "I got to spend a pretty fair amount of time with Woody... He's just the greatest guy in the world. Probably the best thing I've ever done with Woody... was hanging with Paul McCartney. They're really, really good friends."

"So we go to his (McCartney's) house and he makes us veggie burgers. Can you imagine? It was unbelievable. It (burger) was so good. We just sat around and I was in a funk, I couldn't believe I was there with Paul McCartney."

And Stone decided to take advantage of her new friendship when it came to marking her mum Krista's new clean bill of health. She says, "My mum and I are going to get tattoos. We've never gotten tattoos before and probably never will again, but her favorite song is 'Blackbird' by Paul McCartney, (it's) my favorite song as well, and she just went through a pretty crazy two years."

"Two years (ago) she got diagnosed with breast cancer and she's out of the woods now, which is amazing, and so... I wrote a letter to Paul McCartney, asking him if he would draw two little bird feet because he wrote the song, and he sent them to me. He drew two little blackbird feet and so I'm getting the tattoo right there (inside of wrist). He's a good guy!"
