Joining the former child star on the red carpet was her fiancé Matthew Koma, who popped the question in May after collaborating on her 2015 album, Breathe In. Breathe Out.

'Mom and dad are going out tonight!' Hilary - who boasts 27.2M social media followers - Insta-storied from the car.

'It's our first year to attend. We're so excited! So many interesting facts about adoption that I didn't know. It's expensive and so Adopt Together helps families with the whole adoption process especially the financial part of it.

'It's really amazing and the work that they do is so commendable and close to their hearts. So we're so excited to go and support!'

Look lovely in lilac like Malin wearing a jumpsuit by Cushnie

Malin Akerman definitely brought the glamour to the Adopt Together Baby Ball in LA.

The actress eschewed traditional red carpet attire in favour of a striking lilac jumpsuit by Cushnie, and the decision certainly paid off!

This coveted label is renowned for its neck-tie dresses and we are thrilled to see the signature detailing on this all-in-one.

What's more, this exact jumpsuit is available at Farfetch so, if you like what you see, click (right) to bag it now. It is on the pricey side, but with party season approaching you’ll get plenty of wear from it!

If, however, high street price tags are more to your liking, head to the carousel below for worthy variations from I SAW IT FIRST, Lavish Alice, PrettyLittleThing and Boohoo. Complete your outfit with metallic accessories for maximum impact.
