Wilson was hospitalised two years ago (07) when he was found at his home in Santa Monica, Los Angeles after allegedly downing pills and slashing his wrists.
Following the incident Love, who previously dated Coogan, blamed the comedian for Wilson's downfall, saying at the time, "I was just out of rehab, and he was right there with the drugs. I tried to warn Owen. I tried to warn his friends... I hope from the bottom of my heart that Owen stays the hell away from that guy."
Coogan, who starred in Night at the Museum and Around the World in 80 Days alongside Wilson, strongly denied the accusation, branding it "unfounded, unhelpful and hurtful".
And the comic has now blasted reports his career and friendship with the Hollywood actor have deteriorated as a result of Love's claims.
He says, "It was a complete fabrication put out about by someone who had a different agenda. In America they realised it was b******s as soon as they established that it was spread by someone who was trying to throw a grenade in my path. The industry made it very clear to me that they knew, so thankfully it had no effect on my career or my friendship with Owen.
"Yes, Owen did have a bit of a personal wobble between the first Night At The Museum film and the one we've just finished, but he is totally fine now. I spent last Thanksgiving with his family in Texas. We're working together again this year. It never affected my friendship with him at all."
