This will be the Game of Thrones star's first child with her husband Joe Jonas. The couple wed last May in a Las Vegas chapel after the Billboard Awards, where their ceremony was officiated by an Elvis impersonator. A month later, they had a second ceremony in Provence, France.
The surprise wedding happened almost two years after the now-30-year-old singer proposed to Turner in 2017. The couple had been dating a year prior to the engagement. Both shared the same photo of her ring on Instagram.
Turner has kept busy since GoT came to an end. Last summer, she starred in the X-Men film Dark Phoenix as Jean Grey. However, the movie flopped at the domestic box office, a tough break for a superhero project with a $200 million budget.
The Jonas Brothers were nominated for Best Pop Duo/Group Performance at this year's Grammys for song "Sucker." The group celebrated the moment, with Jonas tweeting, "10 years later we are nominated again for a Grammy."
The trio had been previously nominated in 2009 for Best New Artist.
