Hilary Duff smiles as she leaves club with personal trainer Jason Walsh after a night on the town

They appeared to be having really good time at the opening of his new gym.

And it seems Hilary Duff and celebrity personal trainer Jason Walsh enjoyed themselves so much that they held their own after party at the Warwick club on Sunset Blvd in Hollywood.

The friends were spotted leaving the late night haunt separately with the actress-singer smiling and waving before getting into the back of a waiting car on Friday.

Go for a Western vibe in a pair of suede ankle boots like Hilary

After celebrating the opening of new gym with personal trainer Jason Walsh, Hilary Duff changed into something a little more comfortable: A gray T-shirt, a black leather jacket slung over her shoulders, a red clutch, black skinny jeans and the kicker, a pair of two-toned Western-style boots.

Hilary is having a love affair with Isabel Marant as the actress has been spotted in several of the shoe designer's ankle boots of late. On this day, she was wearing the Lance embellished suede and leather style with hardware lining the tops and sides of the boot.

Unfortunately, Hilary's color is sold out, but you can find a dove gray version at Barneys Warehouse. And it's on sale at $469, almost two-thirds off the original price.

If that's still way out your price range, we have more examples below. Check out the bargain at Yoox or the near copy (albeit less Western) by IRO.

Jason tried to keep a low profile but he was spotted in the front passenger's seat of the car with his head down as it sped away.

The 27-year-old had changed out of the little black dress she wore to the opening of Justin's new Rise Nation Fitness Studio in West Hollywood where she mingled with celebrity clients including Ashley Tisdale, Lily Collins and Eli Roth with his wife Lorenza Izzo among others.

By the time Hilary arrived at the club she was wearing a black T-shirt with the word 'crawler' and a snake on the front, black skinny jeans and suede booties. She wrapped a black leather jacket around her shoulders.  

The blonde was also sporting a bandage on her arm, which she hadn't worn earlier. 

The actress and Jason have been the subject of dating rumors in the past, but are now said to be good friends.

The former child star - who shot to fame on popular kids' TV show Lizze McGuire - has been focusing on her career since she filed for divorce from her husband of five years, Mike Comrie, in February.

She shares a three-year-old son Luca with the 34-year-old Canadian former ice hockey pro. 

The star made her musical comeback last year with her album, Breathe In Breathe Out, which charted in the top 5.

And Hilary has also returned to acting, with a role in the TV series, Younger, and a part in movie Path Of Redemption.

The film - due out in September 2016 - also stars Danny Trejo, and pits a young man against the gang who raised him after murdering his parents.
