London, Nov 30 : After scanning the skies for UFOs, Robbie Williams is now planning to look for aliens beneath the waves.

The 34-year-old flying saucer hunter is set to go looking for Unidentified Submerged Objects (USOs) - the official term for water-borne phenomena.

Williams will hire jet skis and go on a 35-mile trip with his mates to spot sea-dwelling extra-terrestrials.

The journey will take him from an LA marina to the island of Santa Catalina off the California coast.

He concocted the scheme after hearing UFO nuts had reported sightings near Malibu of USOs.

“This is mental but I don’t care. We are renting some jet skis and we are going to go from Marina Del Rey to Catalina,” the Daily Star quoted Williams, as saying.

“I heard about these sightings at Malibu of things going into the water. I thought it would be quite exciting to be on a very small object very high over the ocean floor knowing there might be something down there,” he added.

Robbie announced his plan to bosses at the abovetopsecret. com website, to which he is a frequent visitor. (ANI)
