Singer-songwriter Jessie J remembered her ex-boyfriend Channing Tatum on his 40th birthday on Sunday, telling him he’s “truly one of a kind.” The 32-year-old singer took to Instagram and shared a throwback picture featuring the Chaning standing in clear blue ocean water, she wrote, “Happy 40th Birthday to this special man right here. You are truly one of a kind. I am so grateful you were born, and even more grateful we met.” Jessie also posted a video of Tatum taking a leap into the water. “Keep living your BEST life!” the ‘Nobody’s Perfect’ singer wrote. These sweet messages came by the songstress in less than a month after the pair called it quits on their on-again relationship. Jessie and Tatum had reconciled in January after splitting a month earlier.
