Actress Jane Lynch is delighted her idol Olivia Newton-John agreed to a cameo appearance in GLEE - because her dog is named after the GREASE star.
Lynch's character, sports teacher Sue Sylvester, will sing hit track Let's Get Physical with Newton-John in an upcoming episode of the musical show.
And the 49 year old admits it's a dream come true to perform with the singer/actress.
She says, "Sue Sylvester will be singing Let's Get Physical with Olivia Newton-John. I cannot wait to meet her. I met her once at a premiere of a movie she did but this will be (better). I'll get to hang out with her.
"I named my dog after her! I was a huge fan of hers and always loved the name too, so Olivia Newton-John lives in my dog Olivia."
