Haylie Duff reveals she's welcomed second child with fiancé Matt Rosenberg

Haylie Duff has given birth to her second child with fiancé Matt Rosenberg.

The sister of actress Hilary Duff welcomed the newest addition to her family on Tuesday.

She announced the lovely news that she has given birth to a baby girl on social media, and also revealed the baby name they picked - Lulu.

Sharing an adorable photo on Instagram of Lulu asleep in the arms of her big sister Ryan, Hayley captioned the sweet snap: ‘She arrived June 5th, and brought all her magic with her!

‘Ryan is the happiest big sister & we are finally a family of 4! Meet our littlest one... Lulu Gray Rosenberg!’

Fans rushed to congratulate the TV star, with one commenting: ‘Haylie!! She’s beautiful!! Love to you and yours!’

Another said: ‘Congratulations haylie for your new baby is very beautiful!!’

A third added: ‘Congratulations, @haylieduff!! Both of your girls are so beautiful! God Bless!!’

Haylie and Matt have been dating since 2012 and became engaged in 2014.

The former actress confirmed her pregnancy back in January, telling UsWeekly: ‘We are so excited to finally share our good news. Ryan is so excited to be a big sister!’

She added on social media: 'Round 2! Ryan thinks our new baby is growing in HER belly. #FamilyOf4.'

And in March she admitted she was ecstatic for her firstborn to experience sisterhood.

‘Truthfully, we really wanted another girl. My sister and I have such a special relationship,’ she told People of her actress sister Hilary Duff.

‘Ryan could have that bond of sisters. We would have been happy if it was a boy, but we’re pretty pumped that it’s a girl.’

Writing on her blog though, Haylie did admit that she is expecting some tantrums from Ryan as she adjusts to a larger family.

She said: ‘I am fully preparing myself for some lovely meltdowns as she adjusts to becoming a family of four, but for the most part, I think she is going to be an amazing big sister and couldn’t be more excited to see her step in to that role.’

Congratulations to the happy family!
