When it comes to showing off her luscious body in a bikini, Britney Spears has come a long way, baby!

As slender as a Misty Ultra Slim 110 and as cool and smooth as a menthol light, Brit was snapped recently lighting up her backyard stuffing her pretty pink lung pillows and tight little ash into a slinky bikini and sunning herself poolside.

After a crazy couple of years involving mental illness, head shaving, and attacking the paparazzi with an umbrella, Britney's back in shape, and from the looks of it, she's one dirty habit we'd love to get hooked on.

And to celebrate the settlement of her custody battle with ex-husband Kevin Federline, Brit enjoyed puffing on a cigarettewith the help of one of her young sons, who amused himself playing with Mama's lighter.

OK, so Britney still might have a few things to learn about being a mom, but when it comes to being a MILF, she's always hot, hot, hot!
