Just a few days ago she was sitting on the beach, now it is back to the daily grind of an actor.

Halle Berry was spotted out and about in West Hollywood, California, on Monday popping into a costume design showroom.

The 49-year-old star made getting back to work look easy, despite a rather enviable vacation just a few days earlier.

Halle looked effortlessly stylish as she left Bill Hargate Costumes - who are responsible for creating some of Hollywood's best superhero outfits.

The Mobster's Ball star wore a loose-fit tie-dye T-shirt with a pair of distressed jeans and slip-on sandals.

Obviously there for a fitting for a mystery upcoming project, the star kept her head down as she left the studio and made a phone call on her way to her car.

The Oscar winner was solo and without her children, Maceo, two, and daughter Nahla, eight, for a change.

The family, along with Halle's ex Oliver Martinez, were just in Mexico on holiday last week where Halle and Oliver looked more than just friendly exes.

Halle was seen lounging next to the actor with her hand on his bare chest and right over his heart while he gazed back at her adoringly.

While neither have commented on whether their relationship status has changed since when they announced they were getting a divorce late last year, People have revealed that the French star is not ready to give up on their marriage.

A source told the magazine: 'If Halle wants to call [the divorce] off, Olivier would be fine with it because he never wanted the divorce in the first place.'

A second source reiterated that point with People: 'When they first filed for divorce [last October], things were not good. However, the anger went away and Olivier is just very upset about the divorce. He never wanted the divorce and still doesn't.'

But before fans get too excited about a reconciliation, yet another source told the magazine nothing has changed and 'as always they are friends'.

On Monday, the actress declared the couple's son Maceo as her Monday Man Crush and not her estranged husband.

Posting a picture of her son's tiny shoes on her new Instagram account, Halle said: '[Love] my little #MCM.'
