The video shows Ebersol, 32, playing with a little black dog to the tune of Randy Newman's "You've Got a Friend In Me."
He captioned the puppy love with a Bible verse. "We are nothing if we are not a collection of the scars, tattoos, and smiles of a life well lived. I wish for you today, that you find great joy in the joy you spark in others," he wrote. "If nothing else, I hope you're happy just in knowing that you made me happy. It is never lost on me the love with which I have been blessed. For that, I aim to live up to Colossians 3:12."
Meanwhile, Spears showed she was moving on from the breakup by posing with a "Louisiana boy" while wearing a teeny bikini. "So nice to be home!" she wrote on Sunday. "Nothing like Louisiana boys."
The 33-year-old pop star was previously married to Jason Alexander for 55 hours in 2004, and then Kevin Federline from 2004 to 2007. Prior to her relationship with Ebersol and after her broken engagement with Jason Trawick, Spears was dating David Lucado until 2013.
