Whether you believe in aliens or not, many believe we're not alone out there. Here are seven A-list names who claim to have witnessed paranormal activity...
When writing her album Rainbow, Kesha reflected upon an unusual source of inspiration. During a recent interview on the Zach Sang Radio Show, the popstar shared that the record was influenced by an "extraterrestrial" experience she had whilst visiting Joshua Tree National Park in southern California. She revealed that she saw "five to seven" crafts, flying back and forth but was too caught up in the moment to think of capturing the event on camera.
2. Robbie Williams
Robbie Williams isn't just a performer and father-of-two, but also adds alien-hunter to his resume. Back in 2008, the singer shared during an interview that he had met with aliens on three occasions and was considering scouting for extraterrestrials full-time.
"I was at the Beverly Hills Hotel and I was lying on my sun lounger outside at night, looking up," he recalled of one encounter. "Then, about 300 foot above me, there was this square thing which just passed over my head silently and then shot off." While another time, Robbie claimed to have witnessed the moment when "two big massive balls of light started dancing in the sky".
3. Chris Colfer
Chris Colfer claims to have met an alien as a child. During an appearance on The Tonight Show Starring Jimmy Fallon, the Glee star spoke about his fascination with alleged alien and unidentified flying object sightings, and shared his own strong memory of meeting an "alien".
"When I was a kid, I was very sick with bronchitis and I was on sizzurp (prescription-strength cough syrup mixed with soda) levels of cough syrup. So, it might have been a hallucination," he said. "But I woke up in the middle of the night, and there was a little alien standing at the foot of my bed. He was about four feet tall. I'm surprised I didn't scream, but he was just so adorable, he was just so cute, sitting there like, 'Feel better.'"
4. Olivia Newton-John
Olivia Newton-John is also interested in paranormal life after seeing an unidentified flying object as a teenager. In an interview with The Sun in 2009, the Grease star claimed to have seen a silver object flying across the sky at "amazing speeds" near where she lived when she was 15.
"I [saw] one when I was very young. It was unidentified and it was flying," she added. "In England, most people now think UFOs are possible. Twenty years ago, how many people would have thought that?"
5. Kim Wilde
Kids in America star Kim claims to have seen a U.F.O. (unidentified flying object) in her garden back in 2009. The blonde singer saw a flashing light in the sky as she stood with husband Hal and her female friend, and the incident has gone on to inspire her latest album Here Come the Aliens. Kim also believes aliens live among us and are “in despair” over the state of the planet and how we are treating each other.
6. Russell Crowe
Russell Crowe has also claimed to have seen a UFO. The Gladiator star posted a video on YouTube in 2011 in which he alleged showed an extraterrestrial object passing by his office in Sydney, Australia.
"UFO? Time Lapse Photos Outside RC's Woolloomooloo Office (THESE ARE REAL!)" he captioned a 23-second video, which showed a bright light moving over the horizon.
7. Lupe Fiasco
Lupe Fiasco has claimed that he had "an extra-worldly experience" at the age of 11, which left him with scar on his ankle. Back in 2012, the Chicago-raised rapper asserted during an interview on Power 106 FM in Los Angeles that he was resting in bed in the early morning when he was awoken by a bright light and a feeling of being "surrounded by electricity".
"It stops and I look out the window and I see a black disc fly down in front of the window, sits there and then flies out," he claimed. "I had got like a scar on the bottom of my ankle, I don't know where it came from... I never had surgery there, I don't remember falling there."
