Drew Barrymore has paid tribute to her estranged older half-sister, who was found dead on Tuesday (29.07.14).
The 39-year-old actress offered her sympathies to her extended family after Jessica Barrymore, whom she only met "briefly," was found dead in her car in National City, California from a suspected suicide.
In a statement to PEOPLE.com, the '50 First Dates' star said: "Although I only met her briefly, I wish her and her loved ones as much peace as possible and I'm so incredibly sorry for their loss."
Numerous white pills were reportedly scattered on the passenger seat of Jessica's car, but her cause of death has yet to be determined.
Jessica, 47, was the daughter of the late actor John Drew Barrymore - who was also the father of the 'Charlie's Angels' actress - and his third wife Nina Wayne.
John and Drew were also estranged before his death in 2004, as he reportedly abandoned her and her mother, Jaid, when she was just a baby.
The actress, who has two daughters, Olive, 22 months, and Frankie, three months, with her husband, Will Kopelman, has also had a complicated relationship with Jaid and previously called their issues are "my greatest battle."

Kim Kardashian and Kanye West enjoy secret date nights at home.
The couple, who have been living with the reality TV star's mother Kris Jenner in Calabasas, California since welcoming their daughter, North, into the world in June 2013, reportedly hate being apart since tying the knot in May and try to spend as much time as possible together, even though the 37-year-old rapper is currently focusing on recording his upcoming album.
A source told PEOPLE magazine: "They wish they could be together all the time.
"Kanye flies back to see his family every time he can get away, even if only for a night. They see each other a lot more than people realise - they just don't feel the need to publicise it every time."
The insider added: "They really enjoy spending time at home. They watch movies together, play in the nursery ... go for walks around the neighbourhood."
The 'New Slaves' hitmaker, 37, was rumoured to have asked Kim, 33, to put their plans to have a second child on hold so he can concentrate on his career, but the source insists: "They both want more kids. That'll probably happen sooner than later."

Christina Aguilera "felt so much love" at her baby shower last weekend.
The 33-year-old singer, who is expecting a baby girl with her fiancé, Matthew Rutler, celebrated the impending arrival of her second child with 50 close friends at a 'Midsummer Night's Dream' themed bash at her stylist's home in Los Angeles on Saturday (26.07.14).
A source told PEOPLE magazine: "It was a really beautiful, fun night. Everybody gave toasts and Christina gave a speech about how she felt so much love. She thanked everyone for supporting her and said how excited she was to have a baby girl. It was a really sweet night."
The 'Voice' USA mentor, who already has a six-year-old son, Max, with ex-husband Jordan Bratman, wore a figure-hugging white maxi dress and romantic flower wreath in her hair for the whimsical party, where guests played traditional games and sipped on pink Veuve rosé champagne and organic fruit juice before tucking into a delicious cake.
The 'Your Body' hitmaker is also preparing for another major celebration later this year, as she will reportedly marry Matthew in December and is still scouting for an exotic location for their nuptials.
An insider recently said: "They love Hawaii, where they got engaged, but Christina is worries about privacy, so they might rent a private island."

Khloé Kardashian is furious with her friend Adrienne Bailon for branding her younger brother "disloyal."
The 'Keeping Up with the Kardashians' star lashed out at the former Cheetah Girls member, 30, on Twitter after she claimed in an interview that her two-year relationship with Rob Kardashian, 27, had hurt her career.
The 30-year-old beauty tweeted: "Thought her and I were cool SMH (Shake My Head)."
She also retweeted a message from a fan that read: "Adrienne has a lot of nerve to talk s**t about Rob when he is obviously dealing with s**t."
Another fan asked Khloé whether her sister Kim, 33, was "shading" Adrienne when she posted the following tweet earlier today (30.07.14): "So sad when people try to kick my brother when he is down #FamilyForever... Funny how she says being with a Kardashian hurt her career yet the only reason she has this article is bc she is talking about a Kardashian (sic)."
Khloé responded: "Don't think it was a secret. For sure. Don't kick my brother while he's down."
The famous sisters rushed to defend Rob after 'The Real' co-host Adrienne slammed him for cheating on her and admitted she regretted making cameos on his family's E! reality series before they split in 2010.
She said: "To be stuck with that Kardashian label, that was so hurtful to me and to my career."

Kelsey Grammer testified at a parole hearing for his sister's murderer on Tuesday (29.07.14).
The 59-year-old actor, whose wife Katya gave birth to their second child last week, forgave Freddie Glenn for kidnapping and killinf his 18-year-old sibling, Karen Elisa Grammer, in Colorado Springs in 1975, but said he could not endorse his release, as it "would be a betrayal of my sister's life."
During the emotional hearing at the Limon Correctional Facility, the former 'Frasier' star told Glenn: "I accept that you live with remorse, but I live with tragedy every day. I accept your apology. I forgive you. However, I cannot give your release my endorsement."
A spokesperson for Glenn, 57, told the MailOnline his parole request was subsequently denied and he won't be eligible for release again until 2017.
Karen was kidnapped by Glenn and two accomplices while waiting for her boyfriend to finish work outside a Red Lobster restaurant and was repeatedly raped over four hours at an apartment before being brutally murdered.
In happier news, Kelsey's wife Kayte gave birth to a baby boy in Los Angeles last week, whom they are are calling Gabriel even though it is his middle name.
The couple are also parents to two-year-old daughter Faith, while the actor has four other children from previous relationships.

Ian Ziering finds it "torture" being away from his children.
The 'Sharknado 2' star - who plays Fin Shepherd in the upcoming TV movie - admits he hates leaving his two daughters, Mia, three, and Penna, 14 months, whom he has with his second wife Erin Kristine Ludwig, when he goes away to work on projects.
He explained: "Being able to share these experiences with my family makes it even more the worth while. It's tough when I'm away from them though and it hurts.
"That's the sacrifice you have to make as a family and provider. This is what I do for a living, you know. I've always wanted a family and now that I have one, to be away working is like torture."
However, the 50-year-old hunk believes his hard work will pay off eventually as he'll be able to spend more time with them and his wife in the future.
He said: "It's not so often that they're able to travel with me. But I'm working hard now and hopefully what I'm doing now will enable me to spend more quality time with them later."
Meanwhile, Ian - who began acting at the age of just 12 years old and became well known later in life for his role in 'Beverly Hills 90210' in 1990 - isn't sure if he'll want his daughters to follow in his footsteps and have a showbiz career but he insists he'll be supportive of whatever they want to achieve in life.
He told BANG Showbiz: "I'd like them to do whatever they want to do. I'd be supported of whatever goals they're hoping to achieve."
'Sharknado 2: The Second One' airs Thursday 31 July at 9pm on Syfy.

Katy Perry is open to having a baby alone.
The 'Dark Horse' hitmaker, who is currently dating music producer Diplo after splitting from John Mayer earlier this year, plans to have a family even if she never meets the right man, but doesn't want to become a mother in the near future.
The 29-year-old star, who previously admitted she split from ex-husband Russell Brand in 2011 because she wasn't ready to have children, told the new issue of Rolling Stone magazine: "I don't need a dude. It's 2014! We are living in the future; we don't need anything. I don't think I'll have to, but we'll see. I'm not anti-men. I love men. But there is an option if someone doesn't present himself."
Katy's older sister, Angela Hudson, welcomed her first child into the world in February and it made the singer realise she still isn't ready for motherhood.
She said: "I see that my sister is completely devoted to [her] kid, 24 hours a day. And so far, the little girl is so alert, so aware, so conscious, so beautiful, so happy, and I want to be doing that in the right time, and that's not in the next two years, you know? Maybe it's in a five-year plan, but I need to really be able to focus 100 percent of my attention on it. I don't really want to take the child on tour. Not until, like, birth through five is over..."
The 'Birthday' hitmaker - real name Katheryn Hudson - sees a therapist on a regular basis, as it helps her cope with fame.
She explained: "That's a safe place for me to actually work out everything that's going on inside by a person who knows me as Katheryn Hudson. Not as Katy Perry. I would say anyone that's in this business should be doing that regularly -- to have that kind of accountability, because you get to a place where, like, no one holds you accountable. You can do anything you want, and it's so destructive."

Doutzen Kroes has given birth to her second child.
The Victoria's Secret model and her DJ husband, Sunnery James, welcomed daughter Myllena Mae into the world in her native the Netherlands this morning (30.07.14).
The couple, who also have son Phyllon Joy, three, told UsMagazine.com: "Both of our families are beyond thrilled to finally meet our beautiful and healthy little girl. She's a true blessing!"
The 29-year-old star also shared a picture of her entire family on Twitter shortly after giving birth, with the caption: "A miracle saw the light of day this morning."
She added: "Welcome Myllena Mae. Mommy, Daddy and brother Phyllon are super proud!"
Doutzen, who announced her second pregnancy in February, previously admitted she hopes her daughter doesn't follow in her footsteps.
She said: "Though I love my job, I'm not changing the world. I'd love for her to study and to have different aspirations. We need to teach girls they can become presidents, and it's not about beauty all the time."
The top model began dating Sunnery in 2009 and they married in Amsterdam in November 2010.

Robert Pattinson insists he no longer "gives a s**t" that Kristen Stewart cheated on him.
The 'Twilight Saga' star, who split from the 24-year-old actress last year after he struggled to get over her brief affair with married director Rupert Sanders in 2012, says the demise of their relationship was "normal" because they're "just young people."
The 28-year-old British actor told the UK's Esquire magazine: "S**t happens, you know? It's just young people...it's normal! And honestly, who gives a s**t?"
But 'The Rover' star still felt protective over the brunette beauty after they broke-up.
He explained: "The hardest part was talking about it afterwards. Because when you talk about other people, it affects them in ways you can't predict. It's like that scene in 'Doubt,' where he's talking about how to take back gossip? They throw all those feathers from a pillow into the sky and you've got to go and collect all the feathers."
Despite his success, Robert claims he doesn't understand why people are interested in him.
He said: "I don't understand why. I think it goes through periods where you're assigned 'this is the guy to follow'. But whenever I see a bunch of paparazzi hanging out, I always think, 'Oh God, what have they found out!' Oh, that love child! I totally forgot!"
The actor first realised he was famous when he showed up to a nightclub and his name was already on the guest list.
He said: "I was going to clubs in L.A. and you had to call the promoters ahead of time to get on the guest list. But one time I forgot to call, and I was on the list anyway. That's when I knew. I showed up with mustard down my T-shirt and they're like giving me the wink, 'Yeah, man, you're on the list.' "

Kate Bosworth is ready to have children.
The 31-year-old actress thinks raising a child with husband Michael Polish will be "tough" but she and the filmmaker - who she wed last August after a year-long romance - have already discussed how best to approach parenthood.
She told the new issue of Britain's InStyle magazine: "I know that it's going to be tough, but Michael and I will find humour in it.
"We're already convinced that our kids will do things that are hilarious."
And the 'Big Sur' actress says her "maternal instincts" kicked in when she first started spending time with 16-year-old Jasper, her spouse's daughter from a previous relationship.
She added: "After ordering pizza for the third time when she first started coming over, I knew I had to learn how to cook because I wanted to nurture her. These maternal instincts kicked in."
Meanwhile, Kate insists she never follows trends and will only wear clothes she feels comfortable in.
She said: "Early on, I learned not to let someone convince me to wear something - even the coolest or trendiest thing - if I don't feel it."

Jessica Alba loves nachos and tequila.
The 33-year-old star - who has daughters Honor, six, and Haven, two, with husband Cash Warren - is happy with her figure but she doesn't think she's in as good a shape as when she was dancing on a regular basis and claimed her love for Mexican snacks and alcohol may play a part in it as well.
Quizzed on what her favourite sinful indulgences were, she said: "I love nachos so much! And tequila.
"Looking back now, my friends are like, 'Your body was really good when you were dancing. You should do that more often!"
The 'Honey' actress - who is set to reprise her role as erotic dancer and occasional criminal Nancy Callahan in the sequel 'Sin City: A Dame to Kill For' - also revealed that she thinks acting allows her to come to terms with personal issues.
Speaking to Maxim magazine about her acting coach, the brunette beauty said: "She really believes that actors are here to tell stories and to heal people through healing themselves. And she believes every character is about healing something in your life."
She added: "I don't want to talk about my issues. But I definitely feel like I tackled something and came out the other side. Everything that led up to all this was worth it. I'm really comfortable in my own skin, and I'm not apologizing for myself."

Allison Williams will play Peter Pan in a live TV broadcast of the musical.
The 'Girls' actress has been cast as the male protagonist in the three-hour live event for NBC, following on from the channel's successful 'The Sound Of Music' last year, which drew over 18 million viewers.
NBC's Twitter account said: "Dreams do come true! #Girls star Allison Williams will play Peter Pan in #PeterPanLive! (sic)"
A statement on NBC's website read: "Following in the footsteps of the phenomenally successful The Sound of Music LIVE! - which drew over 18 million viewers - comes this musical masterpiece that tells the beloved story of Peter Pan, the mischievous little boy who ran away to Neverland. Get ready for show-stopping stars, stunning costumes, extravagant sets and delightful music that will have everyone in your home singing along."
Allison's casting comes just weeks after it was revealed that Christopher Walken will take on the role of Captain Hook, Pan's nemesis.
NBC Entertainment chairman Bob Greenblatt said: "He's one of the most unique actors in our business. He might really just be a song and dance man at heart... This might be the first tap dancing Captain Hook you've ever seen."
