The couple called things off for good last March, Us Weekly and E! News reported at the time. The actress had been recently photographed getting close to Hedlund in public.

Hedlund dated and was briefly engaged to his "On the Road" co-star Kirsten Dunst for four years before their split was reported in 2016. The actor is best known for his roles in "Pan," "Country Strong" and "Unbroken" and in 2013, joined the lucrative ranks of actors who have become the face of Yves Saint Laurent's fragrance La Nuit de L'Homme.

This will be the first child for both Roberts and Hedlund.
