And the 36-year-old kept herself in the company of her family when she was photographed out in Los Angeles on Wednesday.

Briar Rose, her two-year-old daughter by Hayden, was perched on her shoulders, and Rachel's mother Janice Stango was seen ambling beside them.

Rachel was casually stylish, wearing a grey T-shirt that read 'GYM AND TONIC' and featured an image of a refreshing-looking drink on the front.

Her dark brown hair flung over her left shoulder, the The O.C. star played up her trim legs in a pair of tight faded jeans with the hems folded up.

She accessorized the look with a pair of large, trapezoidal sunglasses.

Meanwhile, Janice had swept her wavy white hair into a massive updo, wearing a summery, multicolored blouse over skintight black trousers.

The sex therapist garnished her look with cat-eye shades, plus a bulging intricately patterned handbag flung cross-body from her right shoulder.

At another point on Wednesday, Rachel defied the heatwave in a grey sweatshirt when she was glimpsed carrying two Starbucks cups into a parking lot.

Rachel and Hayden affianced in 2008, and though they briefly broke the engagement in 2010, they quickly got back together, according to People.

Us Weekly reported their split September 19, with a source dishing: 'She’s full-time back in L.A. He’s in Toronto. They’ve been on the outs for a couple of months.'

Yet they appear to have remained amicable co-parents to little Briar Rose, and were even seen together with her last week.

They way they were: Briar Rose's father is Hayden Christensen, whom Rachel has reputedly split from, per reports last month; they are pictured together in 2012
