Actress Amanda Seyfried will sing a medley penned by Seth MacFarlane in the forthcoming comedy `Ted 2`.

The `Million Ways to Die in the West` actress has impressed her co-star and writer MacFarlane with her `beautiful` singing voice so much so that he wrote a special medley for her to perform in the comedy's sequel, reports contactmusic.com.

`She's going to sing in 'Ted 2'. She has a beautiful voice,` said MacFarlane.

Seyfried said: `He wrote a nice medley, a Ted-ley, but I don't know if I'm up to speed yet.` Mumbai, June 8 (IANS)
