The 32-year-old reality star took to Instagram ahead of the new episode of The Bachelorette, to share a photo of his little boy, Samuel Thomas, decked out in a suit and holding a rose (sort of).
"This week on The Bachelorette...," Sean captioned the hilariously bizarre photo of his son.
The cute couple, who got engaged during the 17th season of The Bachelor in 2013 and tied the knot in January 2014, welcomed their first child on July 2.
The day after bringing baby Samuel into the world, the proud papa shared a snapshot of his cradling his bundle of joy, which he captioned, "My boy and me."
