Sheridan Smith unveils classic name choice for her baby boy on a personalised cake

Sheridan Smith has confirmed the name of her first son two months after she gave birth.

The much-loved actress became a mum in May this year, welcoming a baby boy with her fiancé Jamie Horn during lockdown.

After publicly announcing the news, 39-year-old Sheridan had opted to keep quiet on the details but has now let slip her son's name in a very adorable reveal.

The mum took to Instagram to share a photo of a personalised cake bearing the name 'Billy' in icing.

The delicious looking sponge cake announcing her son's name was carefully decorated with a baby snoozing in a cot alongside iced hearts and clouds.

"Beautiful cake yesterday made for the little man by lovely Cat and @britruevis at @truevisiontv headquarters," gushed Sheridan.

She then teased her next TV project as she added: “We finished our documentary for @itv, can’t wait for you guys to see it!

"Been an emotional rollercoaster but worth every second! #becomingmum.”

Sheridan was last seen starring with her baby bump in ITV series Isolation stories, which was the first TV drama to be made during lockdown.
