The 32-year-old actress and the 'Suits' star - who married in December 2016 after two years of engagement - are reportedly set to become parents for the first time, according to E! News, who claim to have learned that Troian is pregnant.

Speculation that the 'Pretty Little Liars' star was carrying the couple's first child was sparked in late May when photographers spotted the couple on the beach during a vacation in Mykonos, where it was reported Troian was covering up a potential baby bump in a chocolate brown one-piece.

Although E! News have reported the couple are in fact expecting a baby, neither of the pair have confirmed the rumours themselves.

The happy news comes just a few months after the couple were spotted supporting Patrick's former 'Suits' co-star Meghan Markle - now Meghan, Duchess of Sussex - as she tied the knot with her husband Prince Harry on May 19.

Troian and Patrick, 36, are notoriously private about their personal lives, but have spoken out in support of each other's careers in the past.

Patrick recently starred as a "tortured bachelor" in 'Pillow Talk', and admitted in September that his spouse "loves" to see him "get weird" in dark roles.

He said: "It's fun to play this, you know he's a completely different human being than what I've been. I've probably experienced windows of what this would look like, but it's fun to go really dark.

"[Troian] loves this stuff; she gets a kick out of it. She loves to see me get weird. She had fun when I'd come home and tell her what I was doing every day, she was like, 'Okay that's different.' She'd be reading lines with me and she'd be like 'I can't wait to see how this turns out.'"

And he also previously voiced his support for Troian when she made her directorial debut on an episode of ABC's 'Pretty Little Liars' in May last year, during the show's final season.

He said: "Actor. Artist. Rebel. Poet. Dancer. Joker. Dreamer. Friend. Lover. Wife. And now director. Tonight @sleepinthegardn's directorial debut airs. Can't wait to watch it with the rest of the world. Proud of you, captain. Excited to see where the wind takes us next. #pll (sic)"
