The 37-year-old actor, who vowed to never cheat on his childhood sweetheart Joanne Mas again, after she proposed on Valentine's day - was pictured kissing a blonde lady on the lips.
The lucky lady shared the photo on her IG handle and fan came down Danny's neck threatning fire and brimstone.
In his defence he said:
I was accosted by One eager fan who pursued me for a picture but I love my fans so I did no more than take a picture. I treated her to an innocent peck.'
Innocent indeed. Photo of his fiancee after the cut:
