According to a new report, Britney Spears' recent breakup with Charlie Ebersol, 32, had everything to do with the "M" word: marriage.

“Britney had been pressuring Charlie for the last several months about getting married. She is at a point where she wants to have another child, and very much wants to be married again,” an insider reveals to Radar.

But his hesitance ultimately caused the 33-year-old to pull the plug. “She didn’t want to just keep dating him with no plans of getting married,” a source explains.
