Olivia Wilde unveils her stylish new bangs as she hugs Kaitlyn Dever at the Theater Camp premiere

Olivia Wilde debuted a stylish new haircut as she reunited with Kaitlyn Dever at the Theater Camp premiere at Neuehouse in Los Angeles on Wednesday. 

The actress and filmmaker, 39, looked in good spirits as she embraced Kaitlyn, 26, while posing for photos at the event. 

Kaitlyn starred in Olivia’s directorial debut movie Booksmart in 2019, which followed two nerdy high school students determined to break the rules and let loose before the end of senior year. 

Olivia looked incredible after switching up a highlighted hairdo for a darker brunette look and a block fringe. 

She looked effortlessly stylish on the evening as she donned a silk white shirt tucked into a black maxi skirt.

The beauty applied a flawless palette of makeup and toted her belongings around in a black crossbody bag. 

Meanwhile, Kaitlyn looked effortlessly stylish in an all-black ensemble, leaving her brunette locks loose as they cascaded past her shoulders from a center parting. 

At the event, Olivia also posed with influencer Dylan Mulvaney who dressed to impress in a black Prada bralette and shorts. 

Dylan draped a leather jacket over her shoulders and elevated her frame in a pair of silver metallic knee high boots. 

She placed a pair of chic sunglasses on top of her head and applied a radiant palette of makeup including a bold smoky eye shadow. 

Also in attendance was Kristen Bell, who cut a casual figure in a grey shirt and jeans while posing with dapper actor Jimmy Tatro. 

The Bad Moms star tied a colourful striped knitted jumper around her shoulders and accessorised with a peal necklace. 

Meanwhile the American Vandal actor dressed smart in a grey double breasted blazer which he teamed with matching trousers and a white round neck top.

It comes after Olivia spent a bit of quality time with her children in Los Angeles earlier week amid her ongoing custody battle with their father Jason Sudeikis.

She was spotted taking little Daisy, six, and Otis, nine, for a bite of ice cream in the June gloom.

She and Jason have been locked in a protracted bout of legal wrangling over the children, mainly centered on where Daisy and Otis will live.

Her outing comes after she signaled that she bears no ill will toward another ex, pop star Harry Styles of One Direction fame.

Olivia recently liked an Instagram video of Harry singing at Wembley Stadium, proudly posted by his sister Gemma.
