The Hilton family have expanded in recent years with the arrival of two grandchildren for Kathy and husband Richard, 64.

Nicky and her husband, British banking heir James Rothschild, 34, welcomed daughters Lily Grace, three, in 2016, and Teddy Marilyn, 22 months, in December 2017. 

The couple named their second daughter after Nicky's paternal grandmother, Marilyn June Hawley.

Marilyn was the wife of Nicky's late grandfather Barron Hilton - the son of famed hotelier Conrad Hilton, who founded the Hilton Hotel empire. 

Full of praise: Nicky recently said her elder sister Paris will be 'an incredible' mother to her children when her time comes because she's a 'big kid'

She passed away in 2004 at the age of 76 and raised eight children with Barron, who died at the age of 91 in September. 

Nicky and James have been together since 2011 and married in a glittering ceremony at Kensington Palace Orangery in London in July 2015, surrounded by the creme de la creme of British society, as well as their friends and family. 

The Hilton family is soon set to expand further when Paris and Nicky's younger brother Barron, 29, welcomes his first child with wife Tessa Gräfin von Walderdorff, 25, one year after marrying in St Barths. 

Announcing the news via her Instagram page in September, Tessa said: 'We're having a baby!!!!!!!!!!!!! This feels like an absolute dream!

'I cannot even begin to express how much love and adoration I have for this man. And to think that we are now creating a beautiful little miracle between the two of us simply blows my mind.

'We already have so much love for you baby and we cannot wait to welcome you in our arms with hugs, kisses and smiles. This is the most precious gift of all. Our whole world is glowing!'  

Nicky recently said her sister Paris will be 'an incredible' mother when her time comes.

Speaking to US Weekly last month, she said: 'I think she'll be an incredible mother. Paris is like a big kid herself. So I think she’ll be an amazing mother one day.'
