The 39-year-old actress took to Instagram on Saturday (17.12.16) to share the adorable snap of her five-month-old daughter Lula Rose - whom she shares with David Gardner - sitting up for the first time in her "new big girl chair".

Liv - who also shares 17-month-old Sailor with the sports manager, as well as 12-year-old son Milo with former husband Royston Langdon - captioned the photo: "Lula Rose so happy to be sitting up in her new big girl chair she loves watching her brothers and she giggles when they do silly naughty things like kick footballs all around the kitchen @davidgardner (sic)"

And the decision to post the sweet picture comes as the 'Leftovers' star insisted earlier this year that using social media to engage with fans can help her fellow stars get jobs, as Hollywood bosses are more likely to hire someone who will promote their projects online.

Asked if she feels compelled to use social media because of its importance in marketing to Hollywood, she said: "I know that people who have more followers tend to get more jobs than people that don't.

"But some of the most elegant people I know and love would never dream of doing it, some people sort of transcend it."

But 'The Incredible Hulk' actress added that she doesn't feel pressure to "sell things" to her Instagram followers.

She said: "I don't like to feel like I have to sell things on it.

"I mean, you do have to do those things to some extent, but some people that's all they're doing, selling things."
