Sophie Turner is suing Joe Jonas for allegedly refusing to let her take their kids to the U.K.

Sophie Turner is suing Joe Jonas for allegedly keeping their children in New York City even though the couple, who confirmed this month they are ending their marriage, agreed the children would go to England with Turner on Sept. 20.

The family had been spending time in England after buying a home there in March, according to the suit. Turner, 27, was born and raised there and their children are dual citizens. In the suit, the children are only referred to by their initials, WRJ, born in 2020, and DMJ, born in 2022.

In May, Turner began filming a six-part drama series for ITVX, which is the "first significant role [Turner] has taken on since having the children," according to the suit filed in New York.
