How does Britney Spears celebrate having the #1 album in the country and scoring two Top 10 singles on Billboard‘s Hot 100—“Womanizer” and “Circus”—in one week?

With a hearty smile and an Egg McMuffin!

A beaming Brit was snapped with her assistant Brett at Los Angeles International Airport. The pair grabbed breakfast and some OJ from McDonald’s, then met up with Britney’s dad Jamie at the executive first class lounge.

Spears, 27, is jetting off to Japan, where her album just entered the Top 10. She’s set to promote it on the television program HEYx3.

Meanwhile, here in the States, Circus sold 505,000 copies in its first week alone.

Here’s hoping Brit’s black-and-white checkered jacket doesn’t give any of the other passengers on the transcontinental flight vertigo!
