Britney Spears Sexy Bikini PHOTOS: Songstress Rocks Toned Body Poolside during Romantic Memorial Day Weekend Getaway with Boyfriend David Lucado

Britney's back, b#tch - and so is her sexy "Slave 4 U" esque body! Britney Spears took a break from her hectic schedule with new boyfriend David Lucado over the Memorial Day weekend, and dang does the "Toxic" songstress look good! Spears flaunted a skimpy neon blue bikini while chilling poolside with her man at the luxurious Terranea Resort in Rancho Palos Verdes. Brit's toned, curvaceous bod proves that anyone can make an awesome comeback in showbiz - that even means you, Amanda Bynes!

Those hard workouts at the gym seem to be paying off... check it out:

According to reports, Spears is currently preparing to embark on a two-year residency at Las Vegas' Planet Hollywood Resort and Casino starting sometime next fall, so a relaxing LA getaway definitely provided a nice break. Lucado is one lucky guy!

In a recent cover issue for Shape magazine, Spears admitted that getting her body back into tip-top form was pretty hard (especially having to follow a strict Nutrisystem diet):

"I'm doing 90 minutes of yoga twice a week in addition to a lot of cardio - hour-long sessions three times a week with my trainer... The [Vegas] performances won't be simple - they'll be a massive party from start to finish. And to pull this off, I have to be in top condition and running at full speed... I like [dieting], then again, I hate it. I'm in my 30s now, so I have to work harder to keep it up. Dieting is tough... because my specialties are spaghetti, brownies and chocolate chip cookies."

Apparently Spears is happy with the results, and so are her fans!
