Wimbledon 2015: Josh Hartnett, Girlfriend Spotted in Rare Public Appearance, Tamsin Egerton Shows Off Tiny Baby Bump

In a rare public outing, "Penny Dreadful" actor Josh Hartnett was spotted at the spectator's area of the Wimbledon event. He came to watch the tennis match with his girlfriend and future mom of his kids, Tamsin Egerton.

Harnett joined the Duke and Duchess of Cambridge, William and Kate, at the royal box to witness the final match between tennis pro-athletes, Andy Murray and Vasek Pospisil, according to Reveal. Clad in a suit, the 36-year-old actor was seen shaking hands with Prince William when the game was briefly interrupted by rain. His girlfriend, who was wearing a short sleeveless floral dress, was with him the whole time. Her pregnant belly is still a bit tiny, but the two did announce they were in the family way only a few days ago.

"It's true and they are beyond thrilled," the actor's reps said when news of the pregnancy broke, according to Page Six.

Josh and Tamsin have been together since 2012 after meeting on the set of "The Lovers" the year before. Josh, who had previous high-profile relationships with Scarlett Johansson, Amanda Seyfried, Misha Barton and Kirsten Dunst, has kept mum about dating Tamsin for the past four years. "I purposefully didn't want people to know too much about my personal life because I think a lot of people give it away for free," the "Black Hawk Down" actor told USA Today in May.

"I think if you spend too much time courting people's attention into your personal life, you lose your ownership of it. That's why I make sure my life is my own. I was not a dumb kid. I was a little bit wary of this business. I saw what it could do to people pretty quickly," said the actor.

He also doesn't talk about becoming a father all that much, but only hinted how he's preparing for fatherhood when he told Playboy, "I think, Oh shit, there are bills to be paid, and I'd have to get a car that's safe for my kid. I don't have a kid yet, but that's the idea coming into my head these days."

Once touted as Hollywood's next big thing, Josh turned down some opportunities and did away with fame, "Fame can be a dangerous thing. It can destroy you. I used to put myself in positions where I spoke up when I probably should have been listening. When you're young and have convictions, and fame suddenly gives you a microphone, you think, I'm going to tell everybody how it is."

These days, he'd rather keep it low key, "All that matters, I hope, is that that stuff doesn't have any real effect on or dire consequences in my personal life with the people I love and care about," he told Playboy.
