THE Love Don’t Cost A Thing singer made heads turn in the clinging dress after it looked like her zipper could burst at any moment.

The American Idol judge even needed help from a female assistant to secure the zip on the back of her ultra tight outfit.

Her PA thankfully bent over and squashed Jen’s bootylicious curves into the unforgiving dress.

But the struggle continued when Jenny From the Block tried to walk along the street.
