Britney Spears came under fire for forgetting to pay her lunch bill at the Cheesecake Factory, but the blonde beauty insists her security guard is to blame! Spears left the establishment with boyfriend David Lucado, and admits she feels "horrible" about the incident. We can't blame her!

The "Sometimes" crooner told her server her guard would foot the bill, and exited with a doggie bag of leftovers.

In other exciting news, Spears and Lucado might be planning for a baby in the near future!

"Britney cannot wait until the Vegas show is done because she wants to start a family with David. She says she will get pregnant as soon as the show is finished!" a source told Times Live.

"David is always with her in Vegas and they act like an old married couple together. He is really good with her kids and has taken to the father role pretty easily."

Spears made headlines earlier this year when one of her back-up dancers, Dawn Noel, sued after dress rehearsal.

"Although the dance moves were 'fairly basic,' Spears had "difficulty learning the moves and following simple directions," the report reads.

Noel was standing next to Spears when she "twirled in an unbalanced and reckless manner, arms extended out to her sides and forcefully backhanded" her across the face.

Though Spears apologized, she continued with rehearsing while the dancer sought medical attention. Noel says she heard a "cracking sound" and a half hour later determined she had a nasal fracture and needed surgery.

Noel also claims that she, as well as the other dancers, had no problem perfecting the routine.

It was also confirmed the pop star lip syncs during her Las Vegas performances.
