The celebrity gossip blogger spoke often about missing his young son while he was in the CBB house, frequently saying he wanted to leave so he could see Mario Armando Lavandeira III.
And over the weekend, daddy and adorable son certainly looked happy to be back together as they enjoyed a day at Central Park in the snow.
Perez, 36, wrapped up warm in some interesting teddy bear-shaped snow boots(!), while little Jr. Hilton looked toasty in his heavy clothing and furry hat.
The star finished in sixth place on Celebrity Big Brother last week but still emerged as the most talked-about contestant of the series, which has been dubbed The Perez Show by many.
Perez said after his exit he would be taking a few weeks to get back to normal before watching any of CBB back. He said his main focus was spending time with his two-year-old son.
When he was evicted, he carried out a plate with his son's name engraved on it.
In an interview with Huffington Post last year, the celebrity blogger said his life revolved around his child and they'd never been apart for more than two days.
"The joy of being a single dad is getting the love of my son every single day... and the biggest challenge is I put more guilt and pressure on myself because I am his only parent. As a result, my life completely revolves around him. What will make him happiest. And that includes me not being away or travelling as much as I used to. I still have to take the occasional work trip, but we have never been apart longer than two days."
Perez's series of CBB was won by Katie Price.
