While participating in an Instagram challenge where couples were asked to share early pics with each other, the How I Met Your Father star jokingly posted a photo of her husband and his ex-girlfriend Carly Rae Jepsen from the 2013 Grammys.
Hilary then shared a throwback image of herself with and the musician alongside the caption, “Juuuust kidding… Here we are as bbs.”
Matthew also shared a joke of his own, posting a photo of Hilary with her ex Frankie Muniz, who she dated from 2002 to 2004.
And while Matthew may have found his forever in Hilary—mother to his kids: Banks, 3, and Mae, 16 months—his relationship with Carly used to be a musical match made in heaven. (Hilary is also mom to son Luca, 10, who she shares with ex Mike Comrie.)
