Hollywood actor Russell Crowe has posted a video on YouTube claiming that he had seen an Unidentified Flying Object (UFO) over the Royal Botanic Gardens in Sydney.

The Oscar-winning actor said that the video was taken while he and his friend were trying to capture images of fruit bats flying over the botanical gardens outside the actor's office in the inner-city Syndey suburb of Woolloomooloo.

The video was then uploaded on YouTube and the link was posted on his twitter page in which he has commented: "UFO? Time Lapse Photos Outside RC's Woolloomooloo Office (THESE ARE REAL!)."

Crowe then said, "A friend and i set camera to capture fruit bats rising from Botanic Gardens, this was a big surprise."

The 23-second video clip shows a bright, pink object moving across the screen. Russell said that the video was taken using a Canon 5D with no flash, denying that the lights could possibly be lens flares, as suggested by a user. He said, "can't be a lense flare because it moves, camera is fixed."

Some users have criticized the "Les Miserables" actor for posting the video. While some made sarcastic comments, others gave their own explanation for the phenomenon. One user jokingly commented, "Definitely is the real deal. All the signs and indicators are present. blurry, unfocused, 3 frames only, reliable provenance, incorrect exposure factors. All real UFO images are like this," reported The Telegraph.

UFO sightings have become increasingly frequent worldwide, with more people reporting or posting videos of objects moving across the sky. The year 2013 kicked off with numerous UFO sightings.

In January, NASA cameras captured the images of objects of different shapes moving near the International Space Station, a research laboratory orbiting 250 miles above Earth. The same month, a father-son duo spotted two bright objects in the sky in Queensland, Australia. Most of these sightings have remained unexplained.
