Around a million Australians tuned in to watch Seven's Olivia Newton-John biopic on Sunday evening, but the real-life subject wasn't one of them.

In fact, the Grease star says she won't watch the two-part television movie for at least a year.

While the Physical singer has enormous respect for the actors portraying her, she says she has no real desire to see her life translated onto the small screen. At least not yet.

Speaking at Melbourne's La Trobe University shortly before being bestowed with an honorary doctorate, the four-time Grammy winner said she couldn't imagine anyone wanting to watch a dramatised version of their career highs and lows.

"I didn't watch it," she said. "I won't be able to. It's a movie, they weren't there my whole life. They have probably dramatised it ... but I will watch it in a year from now. Apparently the young girl who played me did well [and] Delta is wonderful."
