Julianne Hough, FWIW, had the personal endorsement of Olivia Newton-John.
But Julianne Hough is primarily a dancer. Singing and acting aren’t her forte. I thought she had a nice singing voice, but not a strong one.
Olivia Newton John says she still has the black outfit she wore in Grease. Said she may auction off some day. Kinda make one wonder where the shirt and black tights Ann Margret wore in Viva Los Vegas is. That would be considered one of this iconic type outfits in silver screen lore.
