The 'Ugly Betty' star, who is expecting twin daughters with husband Jerry O'Connell later this year, has decided to pay tribute to her favourite singer Dolly Parton.
She said: "I have been a Dolly fan all of my life. She is a wonderful woman. I really connect with her music and I can't think of a better role model for my children."
Rebecca, who finally met the country singing legend at the 'Backwoods Barbie' show in Tennessee's Dollywood theme park last week, also revealed Dolly was thrilled to discover she had been inspiring baby names.
Rebecca, 35, added to In Touch Weekly magazine: "Dolly has this great, sweet personality but she is also so strong and wise. I got her blessing. She was honoured I had chosen the name Dolly."
Dolly dedicated her song 'Little Sparrow' to Rebecca when she performed it during the show. Rebecca wed Jerry, 34, last summer in an intimate Los Angeles ceremony.
Jerry recently revealed he was doing everything possible to keep his wife comfortable during her pregnancy.
He said: "Having children is something we really worked hard at, and it's just happened. We are blessed."
