Alabama Barker‘s kicking Memorial Day weekend off right … catching a few rays — and baring all while laid out in a steamy photo shoot in her driveway.

The rapper and model shared a series of pics to Instagram Sunday … decked out in some vibrant spring colors — a bright yellow and pink bikini that covered the bare minimum of her body.

Check out the photos … Alabama’s thong-style bottoms are tight on her crotch — only barely encasing her downstairs area.

Barker laid out on her driveway for a few sultry snaps, too … including this one where she flaunts many of her tats including what look like wings on her lower — and, she exposes pretty much all of her posterior.

Alabama’s proven she has no problems baring all in the past … including just last month when she wore a very tight yellow dress to Coachella.

She modeled a swimsuit that provided a bit more coverage earlier this month too … though it hugged her curves in such a way that sorta negated the whole one-piece design.
