Joining them is Taiwanese actress-model Sonia Sui who recently gave birth to a baby girl weighing 3.5kg.
On Wednesday (Feb 1), the 36-year-old shared the good news by posting a photo of her newborn daughter Lucy on her Facebook page.
According to Apple Daily Taiwan, Sui said that she had a smooth delivery that lasted for only an hour.
And it appears that Lucy bears a striking resemblance to her elder brother Max, with their mum quipping that they look like a pair of twins separated at birth.
An earlier Facebook post on Dec 30 last year also showed Sui and her family spending their New Year holiday assembling a pink cot for their new arrival.
Max was born in Singapore in August 2015, eight months after Sui wed American-Chinese businessman Tony Chia.
