A lace wedding dress, a cat lady coat and a circus-inspired ensemble -- stars are rocking all the wrong trends this week!

Adrienne Bailon caught everyone's attention on the red carpet at Effy Jewelry's 35th anniversary in New York City on Monday -- and not in a good way.

"The Real" talk show host donned a white lace gown with a white bodysuit underneath that looked like a cheap wedding dress.
Hailee Steinfeld earned the top spot on our toodrab list this week for the cat lady coat that she wore to Miu Miu's show at New York Fashion Week.

Isn't she a little too young to be devoting her life to a dozen furry felines?

And, Lil' Mama seemed to be channeling a circus ringleader at the premiere of "About Last Night" in Hollywood on Tuesday.

She walked the red carpet wearing an oversized white blouse, too tight yellow pants and odd white knee-high boots, which featured a gold ring instead of a classic stiletto heel. Not to mention, she topped off her look with an orange-tinted, clown-inspired 'do!

It may be time for the rapper to hire a new stylist.

But they weren't alone -- see more of this week's worst dressed stars in the gallery above!
