When John Travolta walks the red carpet – even when it’s not his movie – of course "Summer Nights” has to play 😅 The Grease icon, 72, thrilled fans at the Cannes premiere of Karma with his 26-year-old daughter, Ella Bleu, by his side. The pair are in the French Riviera to launch John's film Propeller One-Way Night Coach – his directorial debut, which also stars Ella. ✨ 📸: Getty #johntravolta #cannes
