Shakira strips down to a satin chemise in a short new ad clip.

The video, an advertisement for Oral B 3D White Whitestrips, had the "Loca" singer losing her scarf and unbuttoning her polo shirt - revealing a lace-trimmed satin nightie underneath.

Shakira's striptease video didn't show any baby bump, though. See for yourself in the video.

A couple of months ago, the singer admitted that she was indeed pregnant with her and Gerard Pique's second child.

"Yes, we are expecting our second baby!! Thank you all for your well wishes!" she said on Twitter.

She recently told Hola! during her perfume launch that they were expecting a baby boy. Their second child would be "a playmate for Milan."

According to Huffington Post, Shakira's pregnancy is going "smoothly", as with her first pregnancy with Milan. This time around, however, she says that she's looking "to take [a] step back from her work," noted the report, citing the singer's interview with Europa Press.

"Now that I'm pregnant I'm trying, for the first time in my life, to not do so many things at the same time. Although, it's always difficult and issues get in the way even when you don't want them to.

"But the majority of the time I do dedicate myself to taking care of my belly, my pregnancy, [and] of Milan," she told Europa Press.

The singer previously joked that she wanted 20 kids with the FC Barcelona center-back.

"With Gerard I'd have 20 children but I don't think I'll have the luxury to do it. For now we're going for the second one, we'll see what happens. We'll see if one day we get a girl. We'll see!" she said, as quoted by Huffington Post.

Shakira also revealed that Pique seems to be doing a pretty good job at being a dad.

"He is very involved with his son. He is always there for him, and that's a big advantage for me as I cannot imagine it any other way," she said, as quoted by Mirror.

The footballer and Shakira have no plans of being married, it seems, saying in the Mirror report:

"We already have what's essential, you know? We have a union, a love for each other, and a baby."

The two have been together since 2010 after Pique appeared in the singer's "Waka Waka (This Time For Africa" video.
