The proud new parents revealed that their baby boy weighed in at 6lbs, 4oz - coincidentally the same birth weight as both his parents - and that both mother and the baby are doing well.
Tanya and Phil revealed the happy news that they were expecting a fourth addition to the family back in April. Tanya also revealed the news during the third season premiere episode of the ITVBe realiy series.
The couple, who have been married since 2014, already also parents to two sons Rocco, 7, and two-year-old Renz. Tanya's 14-year-old teen daughter Gabriella is from a previous relationship.
Last week, prior to the birth of baby Ralphi, Tanya admitted that she was feeling "fed up" of being heavily pregnant, and was more than ready to welcome the newest addition to her family.
The ITVBe reality star also revealed that she had been trying out a new technique ahead of her son's arrival - hypnobirthing.
"My other births were so painful, so I'm trying a different way and hopefully it won't be as traumatic this time," Tanya told HELLO! Magazine.
"When you have your first one you can just sleep all day and rest and it's all lovely, and it's none of that!" she said. "These young kids they don't care if you're pregnant or not, they want looking after."
Tanya Bardsley has been filming the fourth season of the ITVBe reality series and is set to return to television screens this September. The series will see Tanya's pregnancy journey.
