The 34-year-old celebrity blogger initially announced the birth of his son late last month.
At the time, Perez withheld the name of the child along with the identity of his birth mother.
Now however it seems that Perez is more than ready to proudly show off his baby along with his name.
In an article on his site titled ‘Introducing… Perez Hilton, Jnr’ Perez wrote: “We are thrilled to formally introduce you all to the angel we are blessed to have as a son, Mario Armando Lavandeira, III Perez Hilton, Jr.”

In an interview with the LA Times today, Perez revealed that he had always planned to become a father by the age of 35- with or without a partner.
He said: "I knew it was going to happen this way because boyfriends and husbands may come and go, but kids are forever. I didn't want to keep waiting."
He also admitted that having a child was an overwhelming experience.
He explained: "The other day I locked myself in the bathroom and started crying because in addition to my brain feeling loopy, I really have felt super hormonal and emotional.
"Wow, I really am a dad now and it's awesome."
Perez’s initial announcement that he had become a father earlier this year came as a surprise to many with the blogger not previously revealing his plans publicly.He wrote: "I am ready to announce that earlier this month I was blessed with the birth of my first child, a beautiful and healthy baby boy - with lots of hair on his tiny head!
"My family is overjoyed at this newest and most cherished addition ... I am so humbled to welcome this little man into my life. And I am honored and ready for the challenge of guiding him through his."
