John Travolta is sending out encouraging words for his friend Olivia Newton-John.
At Thursday night's L.A. premiere of his movie The Fanatic, Travolta said his Grease co-star "looks incredible." Despite living with stage-four breast cancer, "She doesn't look any different than [she did] years ago, and I'm very proud of her."
For her part, Olivia recently told Entertainment Tonight, "I just want everyone to know, I'm here, I'm doing great. I'm doing really well and I'm really healthy."
