Hanna and Martin Kinsella welcomed a baby boy, Maximus James, in February.
And just eight months later the pair have told OK! Magazine they are expecting their second baby.
Real Housewives of Cheshire star Hanna first appeared on the ITVBe show in 2018, and quickly became a fan-favourite.

Hanna, 32, told OK!: "It was a massive shock, it wasn’t planned at all.
"When I did the test and it was positive, it was just the biggest shock ever - I was so emotional."
Her husband, cosmetic and anti-ageing doctor Martin, 38, added: “It’s happy news. It’s starting to sink in.
“I was really surprised by it, but I was delighted. I really want Max to have a sibling.”
The pair are due to welcome their newest arrival in early May, with just 14 months between the two children.
Hanna said: "They're going to be so close.
"One of the big things I was thinking when I saw that blue line was, 'Oh my God, how am I going to cope?' My life is so hectic as it is with the businesses and filming I just think, 'What am I going to do with two babies?'
“I’m lucky we’ve got my parents and Martin’s parents close by.”
Hanna is a cosmetic dentist and owns several practices, including Kiln Lane Dental in St Helens, which specialises in cosmetic dentistry and facial aesthetics and has worked on many famous faces, including model Danielle Lloyd and Hollyoaks actress Jorgie Porter.
During their son Max’s birth on February 20, Hanna was advised to have an elective c-section, after going 11 days overdue and struggling through a gruelling 18-hour labour.
She added: “I’m going to have a planned c-section, because of the complications I had the first time.
“I had a non-progressive labour and my cervix didn’t even dilate. All of the medical advice so far has been that it's probably better to have a planned c-section, rather than trying to do it naturally again, so I think that’s what we’re going to do this time.”
Hanna was studying dentistry at Liverpool University when she first met Martin.
It wasn't until 12 years on that the former uni friends had a chance meeting in a bar in London and love blossomed in 2017.
The following year Hanna joined the cast of the Real Housewives.
