Jennifer Aniston taped a segment on The Ellen DeGeneres Show the other day, which will air tomorrow. She’s promoting her upcoming film “Just Go With It,” but, among other things, she also talked adoption – and gave a new Chinese gadget a try.

Ellen discovered a little device called Vibrating Bra Inserts through a Chinese informercial and, of course, she ordered it, PopSugar reports.

After giving it a go on her show, much to the delight of her audience, she offered it as a present to Aniston, who was most gracious and tried it on in front of the cameras.

As one of the two videos here will show, the device is supposed to boost breast volume, presumably by boosting blood flow to the area – and, believe it or not, by preventing volume from the breast to fall into the abdomen (a claim made in the informercial).

Aniston was understandably quite shocked when Ellen offered her the “gift” but, never the one to say no to doing something fun, she obliged the talk show host and inserted the inserts into her bra.

In seconds, her breasts were jiggling, which, of course, led to plenty of laughter.

On a more serious note, the actress also rubbished reports that she’s adopting a Mexican boy or a dog, saying her life was quite ok as it was.

“Are you going to adopt another dog?” Ellen asks, with Jennifer replying, “I think you’re confusing that with the Mexican child I’m supposedly adopting.”

She’s not adopting a baby either, she immediately says.

“No, I’m not adopting a Mexican child, but Adam Sandler adopted four last week and that never even got mentioned. No, I’m not adopting any children,” the actress says.

So, with no immediate plans to adopt a child or a dog and after setting the record straight on both rumors, Aniston proceeded to trying out Ellen’s “present” to her.

Check out the two videos here. As usual, enjoy.
