The âRocky' star had earlier slammed Willis, by calling him "greedy and lazy" on Twitter after the âDie Hard' actor reportedly demanded more money for a four-day shoot for the action film.
Stallone said that his outrage was due to frustration and it turned out okay in the end, Metro.co.uk reported.
The 67-year-old actor admitted that he shouldn't have been so vocal about his anger.
Stallone had raised eyebrows after he announced on the micro-blogging site that Harrison Ford will replace Willis in âThe Expendables 3'.u00a0
