He has been working to put his daughters into the spotlight.

The Rocky legend looked as proud as punch as he posed up with his girls, and wife Jennifer, on the pre-event red carpet.

The girls Sophia, 20, Sistine, 18, and Scarlet, 14, were celebrating being on the cover of Harper by Harper's Bazaar, a supplement aimed at younger women.

They were wupported at the event by their 70 year old father and his 48-year-old former model wife Jennifer, who has graced her fair share of magazines in the past.

In addition a veritable stable of fine fillies had turned out for the exciting event, including Victoria Justice,  

The girls' old man has admitted he finds it difficult to get a nap when his youthful daughters are around,

Sly said: 'It's never quiet with you three, which I love. The carnival is always in town.' 

And while they have yet to achieve anything of note, the girls think this actually adds to their allure.

Sistine said: 'I think the Stallone sisters are a mystery, because we are still coming up and nobody really knows anything about us'.

The girls are embracing their sudden fame, however, after first making waves when they appeared at the 2017 Golden Globes alongside proud dad Sylvester Stallone.

Sistine tells the publication, 'I think we're a mystery, because we're only starting up now, ever since the Golden Globes we've got a lot of buzz, and a lot of attention.

'So I think that it's a snowball effect, and we're still gaining momentum in this industry, so I think we're still not really known yet.

'I think that's cool, that we can't start from scratch here, and build up who we are. It's cool, it's the start of something new.'

The girls share the spotlight in the May issue of Harper by Harper's Bazaar, which they also guest-edited.
