LONDON: Hollwyood star John Travolta has become a midnight tennis lover and challenges his staff members to night games.

Travolta, who spent last one year confined at his home in Florida mourning the death of his teenage son, Jett, hasn’t been sitting idle. He has been perfecting his tennis, contactmusic.com reports.

“I took up tennis, I play every day.

I play at midnight — kinda vampire style,” said the actor. “The house manager and the house maintenance person at midnight — we go to the local tennis court,” he added.

Travolta is so much into the game that he is building his own state-of-the-art tennis court at home.
