That's a new look, Adrienne Bailon!
The singer usually opts for long and loose waves but at last night's 40/40 Club celebration the Kardashian pal pulled her hair back into a high bun. The topknot was perhaps a little too tight as the singer's face look taut from the updo, creating a very surprised expression.
Also adding to the new look? The star's extra long lashes, smokey eye and drawn-in eyebrows, which only emphasized her widen eyes. Although this isn't the first time she has tried the sleek updo, it is the most dramatic especially with the heavy makeup.
In addition to her head-turning beauty effect, the star wore a plunging hot pink gown and layered on lots of bling.
What do you think of the star's look?
