Most recently, Gaga came under fire when it was revealed that her charity spent $1.85 million on expenses in 2012 and gave only one $5,000 grant.

We are not a grant-maker that funds the work of other charities, and were never intended to be."
In 2010, Gaga's ex Rob Fusari sued her for $30.5 million over claims she'd cut him out of the proceeds o fher career after he'd discovered her. The lawsuit was dropped when the two reached a confidential settlement.
As part of that settlement, neither she nor Fusari may talk about each other.

If the information were to leak, he claimed, Gaga would make him pay "heavy monetary penalties."

Gaga’s BFF Brendan Jay Sullivan wrote in his book Rivington Was Ours that Gaga had once told him she wanted a nose job and “titty life.” He doesn’t reveal if she followed through on the surgery, however.

In 2013, French artist ORLAN sued Gaga for more than $31.5 million for allegedly plagiarizing her visual work. "Lady Gaga copied the look and style of ORLAN [in promotional materials and appearances for Born This Way]," ORLAN's attorney Philippe Dutielleul told Radar.
