Jacqueline Jossa welcomed her second child - a baby girl named Mia - with estranged husband Dan Osborne last week.
The happy news came after the pair confirmed their shock split in May.
Proud dad Dan, 26 - who is also a father to son Teddy from a previous relationship - announced Mia's arrival on his Instagram page, with a picture of the couple's three-year-old daughter Ella holding baby Mia.
"The star captioned the adorable snap "2/3 of my ABSOLUTE WORLD! Welcome to the world Mia Osborne. Jacqueline did amazing."
Despite a question mark remaining over the pair's future in recent weeks, insiders say Jacquline, 25, is hopeful their new arrival will mark a new chapter for the couple.
A source says: "They're both besotted with the baby, and introducing her to Ella was a really special moment.
"Jacqueline and Dan have been through a lot, but she's told pals she's hoping the new baby will mean a fresh start.
"They still love each other and want to work at being the best parents they can be. Jacqueline's not ruled out a reunion, but wants their focus to be on Mia and Ella for now."
Jacqueline's pregnancy wasn't short of drama. She was reported to have ended her 11-month marriage to Dan in May amid claims he had been unfaithful - which he denied.
Days later, Love Island's Gabby Allen was forced to deny anything was going on with Dan when her ex Marcel Somerville accused the pair - who were pictured looking cosy on a boat in Marbella - of sleeping together.
Insiders also revealed that Jacqueline was fuming when Dan went to Vegas for a stag do just days before her due date.
