Pitch Perfect star Rebel Wilson has announced the birth of her second child just days after giving evidence in her defamation trial.

Wilson and her fashion designer wife Ramona Agruma revealed the exciting personal news via Instagram on Tuesday, disclosing the baby was born on May 4.

She also shared a photo of herself gowned up and with a plastic cap, captioning it “delivery room chic”.

The happy parents have stuck with the ‘R’ theme for the new bub’s moniker, naming her Rose Estelle.

Their first child, who was born via surrogate in November 2022, is named Royce Lillian Elizabeth.

“Proud to announce the birth of our 2nd daughter Rose Estelle! What a gorgeous blessing to have another little girl! Now on May 4th it’s now 4 of us! Ramona and I are feeling so incredibly grateful and blessed to grow our family, thank you everyone for all the well wishes,” Wilson wrote alongside the announcement on Instagram.

Agruma responded to Wilson’s post, commenting “Cheers to our family! It’s 4 of us now”.

Wilson’s Pitch Perfect co-star Brittany Snow was among the first to congratulate the proud parents, writing “Wow! The most beautiful”.

Paris Hilton was also keen to share her best wishes, writing “Congratulations loves”.

Wilson shared a photo of herself with a heavily pregnant Agruma and their daughter, Royce, at Disneyland three weeks ago.

The birth is a happy news for Hollywood star Wilson who travelled from the US to attend her blockbuster trial in Sydney.

She was in the Federal Court to fight allegations she bullied and attacked a young co-star online.

Wilson is being sued by Charlotte MacInnes, the lead actor in the musical comedy The Deb, which Wilson directed, co-produced and starred in.

MacInnes claims she was defamed by the older actor in social media posts that suggested she is a liar and a sellout who withdrew a sexual harassment complaint to advance her career.

The case continues.
