Madonna's teenage daughter is reportedly begging her to end her feud with Lady Gaga.

The iconic singer has previously made veiled comments about Gaga, 26, being inspired by her hits. She even performs a mash-up of two of their songs during her current tour, which is said to have irritated Gaga.

Madonna's teenage daughter Lourdes apparently hates the animosity between the two.

"It embarrassed her hugely that her mother constantly picks on Gaga. Lourdes, who is wise beyond her years, knows Madonna's doing herself more harm than good - and that she'd be better off locking arms than horns with her rival," a source told National Enquirer.

Much has been made of Lourdes' apparent similarity to Gaga, with some saying they look like they could be related. Although her 53-year-old mother isn't too keen on the comparison, Lourdes loves it.

"[She] is a lot closer to Lady Gaga's age than her mom is… and like most girls her age she absolutely adores Gaga," the insider said.
