But Uma Thurman enjoyed a well-earned break from shooting her latest project in Barcelona, Spain, as she took her sweet daughter Luna, four, for a day of fun in the park over the weekend.

Enjoying the sights of the city, the actress, 46, seemed to be having a ball with her little mini-me as they enjoyed some quality time together.

Family fun: Uma Thurman enjoyed a well-earned break from shooting her latest project in Barcelona, Spain, as she took her sweet daughter Luna, four, for a day of fun in the park

Luna's appearance comes amid reports that Uma's ex-fiancé Arpad Busson was trying to prevent her from taking their daughter from New York to Barcelona while the actress films the movie.   

Showing off her recently-dyed raven bob, the mother-of-three rocked leather leggings and boots, layering up in red chunky knitwear.

Wrapping a khaki military-inspired trench around her hips, she carried her adorable daughter along the street. 

This time wearing a black jumper, stylish shades and a lime-coloured scarf, Uma laughed along with her daughter as she pushed the little girl on the swing.

In July 2012, Thurman and Arpad welcomed their daughter Rosalind Arusha Arkadina Altalune Florence Thurman-Busson, who goes by the much shorter nickname Luna.

The Pulp Ficton star began dating Busson two years after her divorce from actor Ethan Hawke.

Thurman married Hawke, 43, in 1997 and they have 18-year-old daughter Maya and 14-year-old son Levon together.

Last month, it was claimed Uma's ex-fiancé Busson was trying to stop the actress from taking daughter Luna to Spain while she films a new movie.

French financier Arpad, 53, filed legal documents to ask a judge to prohibit the Kill Bill star from taking Luna to Europe with her during the shoot.

According to TMZ's sources, the move blindsided Uma at the time, as it was supposedly made two days before she was due to travel.

Arpad reportedly requested that their daughter stay in New York, posing a difficult choice for the actress.

Uma and Arpad will be heading to court in the next couple of months amid their ongoing custody battle over their daughter.

In October, it was claimed that Uma is set to fight her ex on visitation time with Luna which he wants more of.

Sources told TMZ: 'When she and Arpad head to court in a few months, Uma will argue he cancels his scheduled time to see her '7 times out of 10'. 

'Arpad is the one who's asking the judge for more time, but the sources say these are just 'tactics.'

'Our sources say he gets a significant amount of custodial time currently, yet doesn't come close to taking advantage of it.'

Uma apparently wants to co-parent with Arpad but a lot of the time she has to arrange a nanny to take the child to London or the Bahamas where he lives.

The insider added 'he won't take the time to pick her up.'

Arpad reportedly demanded more visitation with the couple’s daughter, less than a year after they reached an initial settlement over the custody of their child.

Arpad filed a motion for temporary visitation rights on August 31. He first filed a custody lawsuit against Thurman in New York in 2014.

The former couple are set to face off in Manhattan Supreme Court by December, according to Page Six.

Arpad has had a rocky relationship with Uma since they first started dating in 2007.

The investor and actress were originally set to be married in 2009, but the wedding was called off, and Thurman returned her eight-carat diamond ring.

In 2011, the couple reconciled and shortly thereafter Thurman became pregnant with their daughter, who she gave birth to in 2012.

Uma and Arpad then were again set to get married, but the actress called off the engagement a second time and the couple again parted ways.

Shortly following their breakup, Arpad reportedly slapped Uma with a lawsuit demanding more custody of their daughter and the power to make important life decisions for their daughter.
