Dier and Leslie Engaged: A Rom-Com Love Story!

On January 29th, 35-year-old Dier announced his engagement to his girlfriend, 34-year-old Leslie, affectionately calling her his "best friend in the universe." He shared images on Instagram showcasing the proposal, including Leslie displaying her engagement ring. Leslie reciprocated the sentiment, posting the same photos and commenting, "Gonna marry my best friend."

Their relationship first appeared on Dier's Instagram in November 2024. The engagement news comes after it was revealed they would both star in the romantic comedy "In Spite of Ourselves." Leslie described the film as deeply significant to both of them.

This engagement follows Dier's prior engagement to actress Haley Lu Richardson. They were together for seven years before Richardson, 30, proposed to Dier in 2019. Richardson recalled the spontaneous proposal occurring while they were eating pizza. The couple quietly separated the following year, with Richardson publicly announcing their breakup in July 2022, stating they had shared a "deeply special chunk of our lives." Dier echoed Richardson's announcement on his own Instagram the same day, confirming their separation two years prior and expressing gratitude for their time together.
