It's A Mystery How Lily Allen Kept Her Nips Under Control Here!

The pasties business is legit.
Lily Allen had us on nip patrol as she tried out a new outfit during her performance at during the charity concert, City Rocks, in London on Tuesday.
The daring songstress donned a beaded, nude Pauline Trigere top from WilliamVintage, which displayed plenty of side boob!
Like really, a lot. It was fabulous! But after careful analysis, no nip slips here.
She also paired the sheer piece with flared Madame Gres trousers, but clearly all eyes are glued upwards so who cares?? Ha!
Okay, in all seriousness though, Lily looked ferocious in this seXXXy ensem!
Thoughts???
