Billie Lourd is handling the death of her mother and grandmother ''very well''.

The 'Scream Queens' star tragically lost her mother Carrie Fisher and grandmother Debbie Reynolds within hours of each other last month but her co-star and pal Glen Powell says the actress is handling it well because she's ''a very strong woman''.

He told Entertainment Tonight: ''I saw Billie last week. If there's anybody that can take something so tragic in their life happening, it's Billie. She's a person who was raised by two very strong women and she's a very strong woman.

''You know, I think she's digesting it very well. She's very emotionally intelligent, and I think she's got a great group of friends around her that are supporting her, and I hope I am one of them.''

It comes after the 24-year-old actress thanked her friends for their support through the difficult time.

Alongside the photo of her and her pals wearing onesies, she wrote: ''This group of onesie clad supremely supportive humans (and many others #notpicturedbutinthepicture) are the kings and queens of my world #greatefulfortheirgreatness #friendsfindingthefunny (sic)''

And in another Instagram tribute to her mother, Billie shared a quote by the Hollywood star and revealed that she will keep her mother's voice ''forever'' in her heart as she learned so much from her.

She wrote on the photo-sharing app: ''If my life weren't funny then it would just be true and that is unacceptable'' - Finding the funny might take a while but I learned from the best and her voice will forever be in my head and in my heart (sic)''

Carrie and Debbie were remembered at a memorial service earlier this month and some of Carrie's ashes were buried with her mother at their final resting place at Hollywood's Forest Lawn Memorial Park.
