Earlier in the day, Jonas took to social media to dedicate a heartfelt tribute to his wife.
“Happy birthday to the love of my life,” the singer, 30, wrote on Instagram alongside a photo of Turner.
“Life is better with you. ❤️,” he added.
Turner's birthday bash comes just a week after rumours began to circulate that the couple was expecting their first child.
“The couple is keeping things very hush but their friends and family are super excited for them,” a source told JustJared, who was the first to report the news. Another added, “Sophie has decidedly been choosing outfits to wear on and off the carpet to accommodate her changing body.”
The 23-year-old actress and 30-year-old actor got married in Las Vegas in May of 2019 and had a second ceremony a month later in France. The couple is yet to publicly address the news.
