Julia Roberts spends quiet family time with mother Betty Lou as they grieve her sister Nancy Motes

They are united in grief following the tragic death of their sister and daughter.
And Julia Roberts and her mother Betty Lou took solace in one another as they spent some quiet family time together on Thursday.
The mother-daughter duo smiled as they watched Julia's sons Phinnaeus, nine, and Henry, six, tear about the public park.
Julia's half-sister Nancy Motes - Betty Lou's youngest child - committed suicide on February 9.

In mourning: Julia Roberts, 46, spent time with her family in Los Angeles on Thursday, a month after her half-sister Nancy Motes died from an apparent drug overdose

Julia cancelled a number of public engagements following her sister's death in order to spend time with her family.
Looking like just another busy mum, Julia took her boys to burn off some energy in the fresh air.

Her mother Betty Lou, who was reportedly diagnosed with lung cancer last year, smiled as she watched her grandsons tear about.
However, the 79-year-old walked with a cane and her daughter placed a protective hand on her back as she guided her over uneven ground.

The August: Osage county actress looked down to earth and casual during her trip to the park, wearing simple blue jeans, which she teamed with a striped T-shirt and blue jacket with matching Converse sneakers.
Julia, who is also mother to Hazel, nine, had her hands full as she juggled her children's brightly-coloured backpacks.
Neither she nor her mother were seen at the public memorial held for Nancy on March 8 by Nancy's fiance John Dilbeck, but friends of the Glee production assistant did attend, including show favourite Jane Lynch.
Julia is said to have held 'her own private goodbye service' with close family.
The redhead has come under fire since her half-sister's death, as it was revealed that Nancy felt bullied by her famous sibling.

Tender: Julia kept a close eye on her mother, placing a hand on her back to guide her over the uneven ground

Tragic: Julia's half-sister Nancy Motes, 38, died of an apparent drug overdose on February 9

'Nancy was proud of Julia but she had severe abandonment issues,' Motes' fiance, John said.
'She had a knee operation as a teen and piled on weight because she couldn't exercise. While her sister was the Pretty Woman, Nancy was an overweight, insecure teenager.’
'Nancy was a tortured soul. She grew up in the shadow of a superstar as a sister and Julia’s fame cast a cloud over her life,' he added.
‘Nancy adored Julia but she became increasingly resentful of the way Julia behaved towards her. In Nancy’s mind Julia was a bully.'
The only public engagement Julia has attended since the death was the Oscars at the beginning of March, and has been seen only rarely in public.
It seems that the star is taking solace in her family instead, and was seen last week dressed in black, picking up her sons and daughter from school.
Fresh from the critically acclaimed August: Osage County, Julia is set to star in TV movie The Normal Heart, about a gay activist raising awareness of HIV/AIDS in the 1980s.

Smiles after sadness: Betty Lou was clearly enjoying the day out with her family in wake of the tragedy
