MMMBop singer Taylor Hanson is expecting his sixth child with wife Natalie Bryant

The Hanson family is expanding!

Taylor Hanson, the middle brother of 90s pop group Hanson, took to Instagram earlier today to announce that his wife Natalie Bryant is pregnant with their sixth child.

The couple already share sons Ezra, 15, River, 11, Viggo, 9, and daughters Penny, 13, and Wilhelmina, 5.

Taylor, 35, shared a cute photo of his wife and five children with his 138,000 followers, and captioned the image: ‘What’s better than being a dad of five? Perhaps being a dad of six. Baby Hanson coming in December and we are over the moon.’

Unsurprisingly, the adorable snap has amassed over 35,000 likes in less than 24 hours, with fans congratulating the 35-year-old singer on his exciting baby news.

‘Beautiful family, congrats on baby 6,’ commented one Instagram user, while another wrote: ‘Congratulations with a new baby on the way, it is truly a blessing.’

A third added: ‘Oh what beautiful news!! Wishing @realnatonthewall best wishes for a safe pregnancy and delivery!!’

Taylor’s wife Natalie also revealed her pregnancy in a separate post, telling her social media followers: ‘Taylor and I are so thrilled to share the news that baby number six is coming this December! Ezra, Penny, River, Viggo and especially Wilhelmina can’t wait to be big brothers and sisters again!’

Speaking to People Magazine, Taylor opened up about how fatherhood has been his ‘greatest adventure’.

‘Natalie and I always kept a love of adventure and pursuit of rich experiences at the heart of our family,’ he told the publication.

‘There’s no greater adventure than welcoming a sixth little person to our tribe.’

Taylor shot to fame in the 90s as a member of Hanson alongside brothers Isaac, 37, and Zac, 32.

The trio have released six studio albums and two Christmas albums since their 1997 hit record Middle of Nowhere. They are beginning their String Theory tour across America and Jamaica in September.
