Sophie Turner and Joe Jonas are reportedly expecting their first child together.

The 23-year-old Game of Thrones star and the 30-year-old singer who wed in Las Vegas last year, are said to be excited about becoming parents for the first time.

A source told Just Jared: "The couple is keeping things very hush hush but their friends and family are super excited for them."

"Sophie has decidedly been choosing outfits to wear on and off the carpet to accommodate her changing body."

Shortly after their wedding in Vegas last May, the couple continued their celebrations with a second ceremony in Sarrians, Southern France.

Guests at the couple's big day included Joe's brothers Nick and Kevin, their wives Priyanka Chopra and Danielle Jonas, and Sophie's Game of Thrones co-star Maisie Williams.
