London: Simon Cowell was stunned when Jennifer Lopez`s marriage to Marc Anthony ended, as he never thought their "bickering" was a sign of more serious problems.
The couple announced the end of their seven-year union last week. They revealed the decision to part ways was "painful" but "amicable".
Cowell was Lopez`s predecessor as a judge on "American Idol".
"I didn`t see it coming. They always seemed to get on. They would bicker, but everyone bickers," contactmusic.com quoted Cowell as saying.
