Pregnant Melanie Hamrick, 29, displays her baby bump for the first time after revealing she is expecting her first child with Mick Jagger, 73

The girlfriend of Rolling Stone Sir Mick Jagger has displayed her growing baby bump for the first time since revealing she is pregnant with the veteran rocker’s eighth child.

Stepping out last week, professional ballerina Melanie Hamrick showed off a rounded stomach beneath the loose fitting white T-shirt tucked into her skinny jeans as she ran errands in New York City.

The 29-year old kept her eyes shielded behind a pair of heavily tinted sunglasses, while a simple black handbag remained slung across one shoulder.

Melanie was seen walking her dog in the city two days previously, but her baby bump was kept under wraps beneath a denim jacket. 

The American is four months pregnant with her first child but it will be a surprise eighth for Sir Mick, 73 – who also has five grandchildren and a great-granddaughter. 

A spokesperson for Mick confirmed the news to The Sun, while a source told the publication: 'This is great news. It will be Mick's eighth child and nothing fazes him. He's been incredibly supportive.

'She's very bright, intelligent, sparky and has her own ideas about how she wants to lead her life.

'She knows what a great relationship Mick has with all of his children and can't wait for him to be a dad again. They are taking the news in their stride.'

MailOnline has contacted a spokesperson for further comment.

Mick and Melanie were first linked in July 2014, when they were spotted canoodling on the balcony of his hotel in Zurich.

Mick has four children - Lizzy, 32, James, 30, Georgia May, 24, Gabriel, 18 - with ex partner Jerry Hall, 59, who is now married to media mogul Rupert Murdoch, 85.

The couple were together for over 22 years but their marriage was later declared invalid and they separated in 1999. 

With wife-of-eight-years Bianca Jagger, 71, Mick had daughter Jade, 44 and with singer Marsha Hunt, 70, he had daughter Karis, 45. 

Good news: Sir Mick Jagger is set to become a father again at the age of 72 with 29-year-old ballerina Melanie Hamrick, with a spokesperson saying: 'Nothing fazes him and he is incredibly supportive'

They said of Melanie: 'She's very bright, intelligent, sparky and has her own ideas about how she wants to lead her life. She knows what a great relationship Mick has with all of his children'

Mick also has 16-year-old Lucas with Brazilian model Luciana Gimenez Mora.

He was famously left devastated when his ex L'Wren Scott, was found dead in her Manhattan apartment two years ago following suicide - they had been together for 13 years. 

And earlier this year Mick - who has five grandchildren and recently became a great-grandfather - introduced the dancer to his kids, when she enjoyed a break with him at his holiday home on the private Caribbean island of Mustique.

However, she reportedly won't be moving to London to live with Mick when the baby is born, although sources say 'he will love and support this child'.

Instead she is believed to be planning to move to either Los Angeles, where he spends a great deal of time, or to Connecticut to be near her family.

In May, Mick's Rolling Stones bandmate Ronnie Wood, 69, welcomed twin daughters, Gracie Jane and Alice Rose, with his wife Sally, 38. 

Now a proud father-of-six, Ronnie appears to also be embracing the role of new father. 

Speaking to Hello! magazine last month he revealed he'd been doing his best to share the burdens of parenthood with Sally, saying: 

‘I’m the burper, walker, nappy changer and I’m still trying to work out when I can get to sleep in between all that.

‘I have played the guitar to them and when I get round to it I will do some drawings. At the moment I’m just soaking up every moment we have.'

Wood previously said that he hoped his good friend, and Rolling Stone frontman, Sir Mick Jagger, would ‘sing lullabies’ to his new daughters. 

The twins are Ronnie's fifth and sixth children, but the first for him and Sally, who is 31 years his junior.
