Everyone’s favorite celebrity train wreck is proving that she’s still chugging along on the pop star track this week. Britney Spears’ new single, “Womanizer” has already been leaked and was even featured in last week’s episode of The Hills. But this Friday, she promises a REAL comeback when the video for “Womanizer” premieres on 20/20.

20/20?!?!?

Yeah, I guess MTV was booked and VH1 wanted to squeeze in another season of The ’80s: Apparently The Greatest Decade Ever. So Brit Brit had to take her comeback vehicle over to that other prime-time music machine, 20/20.

As the world waits with bated breath for the visual celebration of “Womanizer,” let’s take a look at what we’re expecting from the video:

1) Gratuitous shots of Britney’s new-and-improved toned midsection
2) Slithering dance moves (either of the floor or pole variety)
3) Windblown hair and pouty face
4) Submissive guy candy
5) Some outrageous outfit (think “Oops I Did It Again”)

To see if our predictions come true, tune in this Friday to ABC at 10 pm.

“Nice ass, you must walk a lot?”

I just read that a group of researchers at Maastricht University in the Netherlands found that people who walk, and move about more often, had the highest overall physical activity levels.

Before you say “duh”, it gets better. They also found that although the participants (men and women) who ran burned more calories, the moderate exercisers burned more calories overall.

In other words, in the 30 day study, the runners with their laced up, geared up sneaks laid around after they hit the road, and the moderate walkers bounced around a bit more post-workout.

Makes sense… I can recall many a post-job moment when all I did was grab a PB&J, hit the couch and watched Grey’s.

I’m glad I read this news, I was just starting to berate myself for choosing the stroll instead of the run. Also a side note for you… My Biology professor said that you burn very close to the same amount of calories whether you run or walk a mile. The difference is the after burn of a run is greater…it also perks up the ole’ metabolism.

But, hey, lets just keep walking for now.
