He hinted at it
earlier this year, and now John Travolta says he and wife Kelly Preston definitely want to expand their brood.
"I was told by Kelly that at the end of the summer we're going to try," Travolta, 53, told PEOPLE at a Narconon Rehab Center Fundraiser in Honolulu.
Added Preston, 44: "[We'll try] after we finish the movie we're doing together, Old Dogs,
with Robin Williams and our daughter Ella. So after that!"
Travolta and Preston have two kids – Ella Bleu is 7 and son Jett is 14 – but another child has been on their mind.
"I really like having kids. I enjoy their energy and it keeps everything wonderful and hopeful," Travolta, who takes a turn in drag in the upcoming Hairspray,
told PEOPLE in March. "I grew up with six kids in my family. I thought I would have five or six."
