Cameron Diaz outshone by JLo at Hollywood premiere of What To Expect When You’re Expecting

Cameron Diaz and Jennifer Lopez posed side by side at the Hollywood premiere of their hotly anticipated movie, What To Expect When You’re Expecting.

The stars each opted for sexy dresses but in entirely opposing ways, and it was Jennifer Lopez who came top of the style stakes by a long shot.

JLo resembled a Grecian goddess in a floor-sweeping blush-colored gown by Romanian designer Maria Lucia Hohan.

The pleated lamé silk dress oozed sex appeal with a neckline that plunged all the way to the 42-year-old’s waist.

Jennifer Lopez teamed the billowing long-sleeved frock with sparkling caged shoe boots and a clutch bag and bracelet to match.

She completed her elegant look with a sleek ponytail and deep plum lipstick, and arrived at the event with toyboy Casper Smart on her arm.

Meanwhile Cameron Diaz went for a more overtly sexy look in a semi-sheer black knitted dress that clung to her slender figure.

The pleated mini skirt of the frock allowed Cameron Diaz, 39, to bare her endless pins and she accentuated her long legs further with the help of nude Mary Jane heels.

Cameron Diaz kept the accessories to a minimum with just a pair of black teardrop earrings, and she wore pink make-up while keeping her blonde locks loose.

The other female stars also dressed to impress as they arrived at Grauman’s Chinese Theatre to pose on the red carpet this evening.

Brooklyn Decker, 25, was on trend as she opted for a lemon yellow drop waist maxi dress by Giambattista Valli that boasted different patterns on the top and skirt.

Meanwhile Anna Kendrick, 26, dazzled in a taupe dress with sparkling silver embellishment by Elie Saab couture.

Elizabeth Banks, 38, chose a dramatic crimson red dress with black embroidery

The ladies all posed up together at the event and were joined by the movie’s male stars Matthew Morrison, Chace Crawford and Joe Manganiello.

The comedy film, based on the book of the same name, hits cinemas in the US on May 14.
