Parents-to-Be Andy Roddick and Brooklyn Decker Talk Baby Names

Good news for a good cause.

With his charity, the Andy Roddick Foundation, growing and her new show, Grace and Frankie, set to premiere on Friday, Andy Roddick and Brooklyn Decker knew they couldn’t keep their growing family — she’s pregnant! — a secret.

“I don’t know if we would have said anything at all, but with this event and her having to do stuff for her show on Netflix … We figured it would get out there anyway. There was no hiding it anymore,” the tennis star told PEOPLE Monday at the foundation’s 15th anniversary event.

“And, honestly, it drums up support for his organization — if people see the ARF logo behind us, then great. That’s just more support,” adds Decker.

One thing they are keeping a secret: The sex of their baby on the way. “The name is still debatable,” says Roddick. “We’re open to any and all suggestions. We’re going to figure it out as we go.”

While Roddick, 32, and Decker, 28, will both be first-time parents, the Grace and Frankie actress may have a small advantage — or at least a frightening glimpse! — into what’s to come.

“There’s a flashback episode where I’m giving birth in a very dramatic fashion … It was much more terrifying than I anticipated, given [my] current situation,” Decker jokes of the show.

She adds, “I don’t know if it helped prepare me, but it really just made the impending events a little more terrifying.”

The couple were on hand to celebrate the 15th anniversary of the Andy Roddick Foundation sponsored by Retail Me Not, with an evening of festivities that included a performance by Elton John.

“He’s played every odd year for us, since 2005,” Roddick explains of his long-time friend, who also performed at their wedding.

“I got a call in a hotel room in Houston when I was 19 years old … The phone rang and he said, ‘I’m Elton John, how are you doing?’ I said, ‘Great and I’m Paul McCartney‘ and I hung up because I didn’t believe it. He called back and said, ‘No, no, really, it’s been fun watching you for a little bit and I look forward to meeting you in person.’ He’s been a friend of mine … ever since.”

The foundation, which works with communities to offer children safe opportunities outside of school, holds a special place in Roddick’s life, as he started the charitable work at 17 — and found himself relating to much of the youth he was trying hard to help.

“There’s no bad charitable endeavor. The fact of changing the course of someone’s life instead of putting the pieces together afterward, that appealed to me,” he shares. “There’s no magic answer for what’s the best thing or the right thing — it’s just something I was passionate about.”
