Frank and Christine Lampard have become parents for the second time after the birth of their baby boy, who they have given a very special name.

The couple, who have been married since 2015, announced this week that they'd welcomed baby Frederick in an adorable Instagram post, showing the little one snuggled on his mum's chest.

They are also parents to Patricia, who they welcomed in 2018.

And the couple have bucked the trend of celebrities giving their kids quirky names that no mere mortal could get away with, and have instead opted for traditional names with very personal meanings.

Frederick, who they have nicknamed Freddie, is named after Christine's father, Frederick Bleakley.

Patricia is named after Frank's late mum.

When Patricia was just a few months old, Christine spoke about the decision to give her daughter a traditional name.

She said on Loose Women: "It's very old-fashioned, very traditional but it was Frank's mum's name and that's where it comes from.

"Patricia was Frank's mum, who I sadly never got to meet. Frank was obviously incredibly close to his mum and it's one of his biggest sadnesses that I never got to meet her. She passed away the year before we met.

"So we've gone with the traditional grandmother name and it's Patricia Charlotte, which is my grandmother's name."

Christine added: "We've gone very old-school with the name. A lot of people said, 'oh that's a very old name' but there's a link and it means a huge deal to [Frank]."

On Monday night, Christine announced the birth of baby Frederick.

She posted a picture of herself breastfeeding her baby boy as she beamed for the camera.

The snap appeared to have been taken in hospital.

"We are completely in love @franklampard."
