She's a mom-of-one.

The 38-year-old actress paired the look with black pointed-toe pumps and went without jewelry altogether.

She wore her brunette tresses in a simple chignon, allowing wavy strands to fall in front. 

Bilson enhanced her natural beauty with minimal makeup including a sheer orange gloss and a light touch of brown eyeshadow.

Bilson opened up to Bachelor alum Nick Viall on The Viall Files podcast in July about what it's like to date as a single mom.

The OC vet shares daughter Briar Rose with ex and fellow actor Hayden Christensen, 38.  

She revealed that she hasn't introduced anyone to her daughter yet since splitting with Christensen in 2017.

'She has not met anyone as of yet and it would have to be someone I know I’m going to be with,' she told Viall. 'It would have to be a very serious relationship.'

Though still has yet to acquaint her dates with little Briar, she still makes the little girl a focal point of conversation. 

'I always put it out there,' she said. 'She’s my world and I talk about her all the time anyways. How f***ed up would it be if I hid that? … If you’re going to pursue something with someone, they have to be interested in the kid or be willing to be around the kid or babysit the kid … all the things.'

And anyone who fails to ask about Bilson's daughter will get themselves marked off her list.

'I was talking to this guy a few months back,' she said. 'Anytime I would bring my daughter up, [he] would never pursue the question or ask more about her.

'It was a red flag because anyone that you’re going to get involved with, if you have a kid, they have to be all about the kid.'

She also gushed over a special privilege that kids provide when it comes to breaking plans.

'Kids are great for an excuse for anything,' she said. 'If you don’t want to do something, you don’t ever have to lie because like you have kids.'

'You can leave early, you can not go and you can go to bed at 9 and it’s awesome.'
