Alex Rodriguez's wife Cynthia Rodriguez - who has been staying at Lenny Kravitz's home in Paris, France, since Tuesday - has "strong suspicions" about Madonna and her estranged husband's "friendship" with the singer.
"She doesn't believe they are just friends," says an insider quoted by Us Weekly.
"Something deeply suspicious is happening here. Cynthia did indeed leave [New York City] because she is convinced this is all true."
Cynthia Rodriguez, 34, and Alex Rodriguez, 32, have split up after "three months of problems," the New York Daily News reported Wednesday.
She stood by him last year amid his infidelity with manly stripper Joslyn Morse. But the final straw in their relationship was apparently Madonna.
Specifically, that A-Rod was making late night visits to Madonna's pad - including right after C-Rod gave birth to their second child.
Thursday, a source said: "[Alex Rodriguez] literally left 10 minutes after the baby was born (this April), and was at Madonna's. It's true. It's crazy."
Whether or not they are having affairs, Cynthia is definitely out of the U.S. She was spotted outside of Lenny Kravitz's Paris home on Tuesday.
Kravitz today denied any role in A-Rod's marriage drama, but admitted that Cynthia came to stay with him to get away from everything in N.Y.
