The bouncing baby boy will be the first child for Tony who was previously married to Desperate Housewives actress Eva.
Eva and Tony separated in 2010 and their divorce was finalised in early 2011. Tony allegedly cheated on her with the former wife of one of his teammates, with whom the couple had frequently socialised together.
The 38-year-old Latina beauty said she suspected infidelity after finding text messages between the pair on Tony's phone.
They cited 'irreconcilable differences' as the reason for their split.
Eva and Tony's idyllic nuptials took place just outside Paris in the summer of 2007.
Eva's split from Tony was her second divorce. The actress was previously married to General Hospital star Tyler Christopher.
The couple wed in a Las Vegas ceremony in 2002 but split after two years, with Eva citing her youth as one of the main factors.
Eva was recently spotted with Penelope's younger brother Eduardo Cruz who has been her on-off beau since 2011.
The pair were seen having lunch together in New York on Saturday.
"After a bit, they started holding hands and kissing," an onlooker told E!. "Then they began full on making out. They were seated a table out in the open at the front of the restaurant. They didn't seem to care who saw them."
