After co-starring in the film The To-Do List with Rachel Bilson, Hader began dating her in 2019. The couple made their debut appearance at the 77th Golden Globe Awards in 2020, but it was announced in July 2020 that they had split up.
Hader married Maggie Carey, a writer, and filmmaker, in 2006. Their three daughters are Hannah, Harper, and Hayley. Hader filed for divorce in December 2017, following the couple’s breakup announcement in November 2017. The uncontested divorce was negotiated in March 2018, and it was finalized three months later.
There are reports that the actor is dating Anna Kendrick in late 2020 or early 2021. Someone revealed that the couple has been dating quietly for a year. They both appeared as co-stars in the Disney + Christmas feature Noelle.
