Annie Lennox's model/artist daughter Tali Lennox posted a moving tribute via Instagram to her boyfriend, Ian Jones, who went missing in a kayaking accident three days ago and is presumed dead.

On Monday, authorities announced they'd recovered a unidentified body from the Hudson River, but the Dutchess County Sheriff's Office told People there was a "strong possibility" that it was the 32-year-old.

While there's been no official statement, Lennox's heartfelt Instagram post has all but confirmed the model/artist's death.

On Saturday morning, the couple went kayaking and their boat overturned, said Capt. John Watterson of the Dutchess County Sheriff's Office. Unfortunately the two were not wearing life preservers when they fell into the water, Watterson said.

Jones' mother, Sherron Jones, said the two, who had been dating for two years, had been up all night attending a party at the River-front mansion of hotelier André Balazs when they impulsively decided to take a two-seater kayak on the Hudson early in the AM.

Authorities say alcohol may have been a contributing factor however, his mother insists the photographer had been sober for four years.

"He gave his life to AA," she said. "He was not drinking. He only drank water. He was so strong and healthy."

What a sad story ...
