Liam Neeson's nephew has reportedly suffered a "serious head injury."
The 'Taken 2' star, who was left devastated after his actress wife Natasha Richardson died from a brain injury following a skiing accident in Montreal, Canada in March 2009, has been in contact with his family since learning his sister Bernadette Sexton's son, Ronan Sexton, is in a "critical condition" in hospital.
A source told the MailOnline that Mr. Sexton fell from the top of a telephone box in Brighton in East Sussex, England during a night out for a friend's 30th birthday and was rushed to Hurstwood Park Hospital in Haywards Heath, West Sussex.
Bernadette's partner Harry Shannon confirmed she was "in hospital with her son" today (26.06.14).
He added: "Bernadette is not in at the moment because she has been at the hospital all day in Haywards Heath visiting Ronan. I do not want to comment further."
Earlier this year, Liam, who lives in New York City with his sons, Micheál, 19, and Daniel, 18, admitted he is still grieving for their late mother.
The 62-year-old star said: "[Her death] was never real. It still kind of isn't. There's periods now in our New York residence when I hear the door opening, especially the first couple of years . . . anytime I hear that door opening, I still think I'm going to hear her."
He added: "It (grief) hits you. It's like a wave. You just get this profound feeling of instability . . . the Earth isn't stable anymore and then it passes and it becomes more infrequent, but I still get it sometimes."

Demi Lovato's boyfriend makes a cameo in her new music video.
The 21-year-old singer unveiled the video for her duet with Cher Lloyd, 'Really Don't Care,' today (26.06.14), which features a number of other celebrities, including Travis Barker, Kat Graham and her on-again, off-again beau Wilmer Valderrama.
The brunette beauty can been seen cosying up to the former 'That 70s Show' star as he wraps his arms around her with a huge smile on his face in the brief scene.
The 34-year-old actor quietly rekindled his relationship with the former 'X Factor' USA judge in February 2013, but they rarely discuss their romance.
They first started dating in 2010 shortly after Demi's split from Joe Jonas. They split up after a few months but were linked again in 2011 before they split again.
Wilmer, who previously dated a string of other famous women, including Lindsay Lohan and Ashlee Simpson, sparked rumours he was planning to propose to the singer in December after he was spotted buying a diamond ring from Tiffany & Co., which he had engraved with a special message reading, "With you and by you always."
His appearance in the video indicates their relationship is still going strong, but Demi admitted that her new song was originally a "breakup song."
She told E! News: "When I originally wrote it, it was a breakup song. But now I have sung it so many times that it kind of no longer has a significance in that sort of way. When I sing it, I always want to inspire and empower."

Maksim Chmerkovskiy thinks Jennifer Lopez is the perfect woman.
The 'Dancing With the Stars' performer, who enjoyed a "very flirty" night out with the 'Booty' hitmaker in Connecticut last Saturday (21.06.14) after denying rumours they are dating on Twitter earlier this month, reportedly wants them to be more than friends, but is trying to respect her space so she can get over her recent split from Casper Smart.
A source told PEOPLE magazine: "[They] are just friends, but I'm sure he'd love it if they were more.
"He really likes her. He thinks she's beautiful, really cool and down-to-earth."
The duo were first introduced by Jennifer's close friend Leah Remini, who bonded with the professional dancer, 34, while appearing on the US dancing series last year.
The 'First Love' singer danced with Maksim - who previously dated Kate Upton - at the American Music Awards in November and they were "inseparable" at his brother Val's birthday party in Los Angeles in March.
The 44-year-old singer, who has six-year-old twins, Max and Emme, with ex-husband Marc Anthony, recently revealed wasn't looking for a new romance.
She said: "I'm good right now. Let's just say we just got out of a relationship. There needs to be time for reflection and alone time."
But the 'On The Floor' star previously admitted that she's "one of those people who doesn't like to be alone."

Cilla Battersby-Brown is to return to 'Coronation Street'.
Wendi Peters is set to reprise her role as the loudmouth mother of Fiz Stape and Chesney Brown for a short stint, it has been announced.
Cilla will return to Weatherfield after a seven-year absence for six weeks in October as part of an exciting new storyline.
While plot details are being kept under wraps, Cilla's cobbles comeback is expected to tie in with Fiz's departure from the street as actress Jennie McAlpine goes on maternity leave to welcome her first child.
Wendi said: "I'm really thrilled to have the opportunity to revisit Cilla and the cobbles for a short while and to see what she has been up to for the last seven years."
'Corrie' executive producer Stuart Blackburn added: "We can't wait to see Cilla back on the cobbles, she's a truly unforgettable character who is at the heart of Corrie's rich history."
Cilla first caused havoc in Weatherfield between 2003 and 2007, when she left the street after inheriting a £450,000 necklace from a pensioner who died whilst in her care.
The brash character was last seen in the 2008 DVD special 'Out of Africa'.

Shailene Woodley finds fans "strange".
The 'Divergent' actress admits she finds it hard to relate to the obsessive "screaming fandom" she sometimes encounters as she never felt that way about celebrities when she was younger, so she tries to "remove" herself from such encounters.
She said: "The whole fan thing is very strange to me, because I've never had anybody that I have gone crazy for, like whether it was an actor or a musician.
"And so it's a weird thing for me to relate to, especially the screaming sort of young fandom, the 'Twilight', 'Hunger Games', 'Divergent' world caters to.
"So I kind of actually try to like actively remove myself from the situation. There's this idea that actors and that musicians or models or whatever are better than the fans, and the fans look up to them because they're an actor. People that I look up to in life are people who make a difference, and brave, strong women."
"I've met people where I'm like, 'Hi, I'm Shai,' and they can't even see me because they're screaming, and I'm making eye contact with them, but they're not there. And that, to me, is weird."
The 22-year-old star doesn't try to be a role model but is happy if some of the ways she lives her life will inspire others.
She added in an interview with the new issue of Vanity Fair magazine: "I don't know how quite to do that except remove myself from the situation and live my life, and if that inspires people, then I guess that's what a role model is.
"The greatest people who have inspired me in my life don't go out trying to be a role model. They just are devoted, and they're not afraid of what other people think of them."

Jared Leto and Ellen Page have been named Sexiest Vegetarian Celebrities by PETA.
The 'Dallas Buyers Club' actor picked up the animal rights organisation's male prize ahead of fellow non-meat eaters Joaquin Phoenix, Samuel L. Jackson, Peter Dinklage and Woody Harrelson, while the 'Juno' star triumphed ahead of Ariana Grande, Jessica Paré, Laura Prepon and Sarah Silverman, E! News reports.
Jared, 42, has previously credited his vegetarian diet for his youthful looks.
Asked how he stays so young looking, he said: "I'm pretty healthy so I think that helps a lot. I've been that way for a long time - 20 solid years of eating vegetarian/vegan and taking care of myself."
Meanwhile, 27-year-old Ellen has also spoken out to slam critics of vegans.
She previously tweeted: "Why are vegans made fun of while the inhumane factory farming process regards animals and the natural world merely as commodities to be exploited for profit?"
Jared and Ellen follow in the footsteps of the likes of Leona Lewis, Russell Brand, Kristen Wiig, Olivia Wilde, Natalie Portman and Carrie Underwood in receiving the titles from PETA.

Rob Lowe and his family have been rescued from floods by emergency services.
The 'Parks and Recreation' star has been vacationing in Grasse, France with wife Sheryl Berkoff and son Johnny, 18, and their idyllic break took a nightmare turn when torrential storms struck overnight.
Posting images from the property on Instagram, Rob wrote:
"This is right outside the house. Was twice as high at the worst, just before sunrise."
His son also posted a video on the site, adding: "That's the first floor of our house submerged. Scariest hour or so of my life."
According to local residents, as much rain fell in four hours that usually falls in four months, causing mudslides, road washouts and power disruption, but thankfully emergency services were on hand to help those stranded and Rob and his family paid tribute to their rescuers.
Johnny tweeted: "Thank you to the fireman that saved us from this nightmare. Happy for us all to be safe, thoughts to others."
In a picture that has now been removed from Instagram of Cheryl hugging a fireman, the 50-year-old actor wrote: "My wife being rescued this am in the horrific flooding in Grasse France. Glad we are safe. Grateful to first responders."
The former 'West Wing' star wasn't the only person in the area to need help.
One rescue official told People: "This was the biggest storm of the year. Water rising like that can be terrifying. There's only one rescue station in Grasse, and this storm required assistance from several other regional units. We were called out on a lot of emergency rescues yesterday."

Adam Levine loves being famous because someone else does his laundry.
The Maroon 5 frontman has always hated washing his clothes so was pleased to become successful enough to pay someone to do his chores.
He said: "You know what the greatest thing about what's happened to me is? I don't have to do my own laundry. I'd always think to myself, I can't wait for the time when I don't have to do laundry anymore."
Despite his global stardom, the 'Moves Like Jagger' hitmaker knows he owes some of his success to good luck.
He told the new issue of America's GQ magazine: "I've worked hard but I've also had a lot of wonderful things happen to me. I haven't been dealt a hard hand."
The 'Voice' coach always wanted to be famous for his music, and thinks too many people now are only interested in being well known, rather than having a talent.
He said: "I wanted to become a successful musician. It wasn't like now, when kids are like, 'I want to be a famous sl*t. Or whatever I can possibly be famous for.' I wanted to be a famous musician."

Britain's Princess Anne is to open a £2.5 million water sports and leisure centre in Peterborough next month.
The 63-year-old royal - the daughter of Queen Elizabeth - will officially open Lakeside at Ferry Meadows in Ferry Meadows Country Park on July 8.
The Princess will be given a tour of the new facility upon her arrival and will also get to meet groups of board members, staff, tenants and volunteers during her visit.
She will also get a chance to meet volunteers and the users of Peterborough Sailability, which provides sailing for people with disabilities and carries out Vivacity Adapted Cycling schemes.
At the end of her visit, Anne - who is the Patron of the Royal Yachting Association Foundation - will unveil the plaque at the front of the new centre, before Nene Park Trust Chairman Jon Marsden will deliver a short speech.
Children from local schools have been invited to attend the opening along with friends and family of the park, but officials of Nene Park Trust, which operates Ferry Meadows, insists there is limited room for spectators.
The new centre is home to Nene Outdoors, which is a new water sports venture, and Lakeside Kitchen and Bar, which offers dining and function facilities at the park.

Julian Fellowes has hinted there could be more death on the way in 'Downton Abbey'.
While actress Lesley Nicol - who plays cook Mrs. Patmore - recently assured fans no major characters will die in series five, the show's creator and writer is keeping the cast on their toes as they have yet to receive the scripts for the final episodes.
Quizzed about Lesley's comments, he told the Daily Telegraph newspaper: "That's all you know! You see, I only finished the last script on Tuesday."
Lesley claimed there were no plans to axe any further characters after the show received fierce backlash for killing off fan favourites Matthew Crawley and Lady Sybil in the third series.
She said: "There aren't any plans for any big characters to die this year. There has been such a big fuss in the past, especially with Matthew Crawley.
"I think it would be very unwise to do any more deaths because the viewers don't like them."
While she may not meet a grisly end, youthful Crawley cousin Lady Rose is expected to be written out of the ITV period drama in the upcoming fifth series.
Actress Lily James is to leave the show in order to promote her upcoming Disney movie, 'Cinderella', around the world.
The promotional duties mean Lily, 25, will be unavailable when series six is filmed next year, but it's thought Julian will keep the door open for her to return in future.

Sinitta is to meet with 'X Factor' bosses to discuss her role on the new series.
The flamboyant singer - who has previously acted as show boss Simon Cowell's right-hand woman - has revealed she will sit down with producers this week regarding her future on the ITV talent competition and hopes to take on a mentoring role.
Appearing on ITV's 'This Morning', she said: "I'm having a meeting, actually, to discuss what is going to be happening this year. I don't know exactly what I'm doing but I'd like to be back in my old role working with the contestants and working with the talent, I loved doing that."
The 45-year-old star also expressed her desire to perform on the 'X Factor' live shows as a special guest to promote her comeback song, 'So Many Men, So Little Time'.
She said: "I could perform it and come through the doors ... I would love that because I'm not going to be a judge, let's face it. That hasn't happened yet, has it?"
Sinitta, who has been part of Simon's inner circle for two decades, admits her music mogul pal has yet to listen to her new song and she's anxious to hear his opinion.
She added: "Simon was sent the single yesterday and I'm not sure if it's a good thing or a bad thing, but I haven't heard [what he thinks of it]. I have said, 'Just say what you think!' But it's done and it won't change anything whether he likes it or hates it because the record is made now. But he loved the original, so I'm hoping [he'll like it]."

Steven Moffat has joked the Doctor's real name is Mildred.
The 'Doctor Who' executive producer, who took the reins of the BBC sci-fi drama in 2010, claims the popular character's real identity - which has been shrouded in secrecy since the show first hit the airwaves 50 years ago - is only divulged to the most senior of staff.
Writing in the new edition of 'Doctor Who' magazine, he quipped: "No one can know the Doctor's name, except each successive showrunner. We're taken into a special room far beneath the BBC and given the ancient and special runes that spell his true and awful name.
"We're commanded never to reveal what we have learned, because then the show would have to be renamed 'Mildred'. Oh, bugger!"
Steven is currently hard at work on the upcoming eighth series of 'Doctor Who', which will see Peter Capaldi take over the role of the Time Lord.
The 56-year-old actor will be joined by a host of big names on his first adventures in the TARDIS.
Guest stars this series include comedian Frank Skinner, 'Line of Duty' star Keeley Hawes, 'Death in Paradise' actor Ben Miller and singer Foxes.
The Doctor will also come face-to-face with a familiar nemesis from his past as it's rumoured producers are bringing back the villainous Master, last played by John Simm.
