Although the star hasn't opened up about exactly what she's going through, she did explain that Jake Gyllenhaal was helping her through her sadness.
The Bridesmaids actress took to Instagram to share a photo of a sketch that Gyllenhaal had drawn for her on the night that she was attending his Broadway play, Sunday In The Park With George.
"Well this really cheered me up after a crap couple of days and was very moving," she wrote. "Thanks Jake Gyllenhaal, @annaleigh_ashford and the amazing cast of Sunday In The Park With George. I will treasure this sketch x".
Wilson is currently filming the third instalment in the Pitch Perfect franchise, Pitch Perfect 3.
