Stars light up Halloween ball

Guy Ritchie and Hugh Grant were among stars giving a fright at the UNICEF Halloween Ball Thursday night.

Journalist Jemima Khan hosted the bash at London event space One Mayfair, where some stars were barely recognisable as they walked the blue carpet, UK newspaper The Mirror reports.

Guy, with his son Rocco, dressed up as the meth-making characters from hit TV drama Breaking Bad, donning yellow jumpsuits and breathing masks propped on their foreheads.

Guy went as far as to add facial hair mimicking dad-turned-drug dealer Walter White, played by Bryan Cranston, while Rocco went as Aaron Paul’s character, Jesse.

Jemima went for a caged woman and gorilla costume, while her ex, Hugh, covered his face entirely, donning a large horse head he paired with a suit.

Bradley Cooper’s model girlfriend Suki Waterhouse was also in attendance, wearing a “creepy Halloween doll” get-up, according to the outlet.

Proceeds from the event will be donated to UNICEF’s efforts to protect children in war-torn Syria.

“After 3 years of conflict, more Syrian children than ever before need our help,” reads a statement on the humanitarian organisation's website.

“Millions of children in Syria and the surrounding region are in danger. They face losing their homes, their families and even their lives. Torn from everything they know, they're left vulnerable to many other dangers, from disease and malnutrition to violence and exploitation.

“Unicef will not stop until every child is safe,” workers vow.

“We are working around the clock in Syria and the surrounding countries to provide children who have suffered so much with crucial and life-saving supplies such as clean water, medicine and psychological support.”
