Dustin Lynch and Kelly Osbourne are adding more fuel to the fire of dating rumors with a new Instagram video.

The video, posted by Osbourne on Monday (April 3), shows her and Lynch blowing out a candle on a piece of cheesecake with a caption that reads, "With my boo @dustinlynchmusic #celebrating our first anniversary! #TheOddCouple," as both of them hold up their fingers in a No. 1 sign.

The two met last May after Lynch performed a set at the 2016 Stagecoach Festival in California. Rumors started swirling when Osbourne posted an Instagram photo saying the country star was her "boyfriend," which was preceded by another Instagram shot that appeared to be taken on the singer's tour bus, with Lynch and Osborne holding Dixie cups.

"Thank you @dustinlynchmusic & everyone on your team for treating me like family!" the former Fashion Police panelist wrote in the caption.

But both individuals insist, still, there is nothing romantic going on between them, with Lynch confirming that the two are only friends. “I can confirm that we’re friends," the "Seein' Red" singer told Taste of Country in 2016, revealing that the two bonded after his Stagecoach set. “We hit it off and hung out that night and watched Little Big Town and Luke (Bryan) together and had a blast. I can deny the rumors that we’re hooking up or dating or pregnant."

Lynch recently celebrated his fourth No. 1 single with "Seein' Red." His current single "Small Town Boy" serves as the second single off of his upcoming album.
