Best Dressed at 100th Anniversary of Beverly Hills Hotel: Stana Katic and Cat Deeley Dazzle [SLIDESHOW]

The 100th anniversary party for the Beverly Hills Hotel in Beverly Hills, Los Angeles, saw some of Hollywood's biggest stars come out and play. Everyone from television star Stana Katic to Russian ballroom dancer Katrina Smirnoff was present. The hosts for the evening were director Brett Ratner and Warren Beatty and the entertainment was a performance by Mary J Blige.

"The Canadian actress (Katic) wore Stella McCartney. Stana hit all the right notes with her sexy, plunging neckline jumpsuit. Tousled, wavy hair, a gold clutch, and green heels complemented Stana Katic's Beverly Hills Hotel outfit," Celebs Gather reported.

Meanwhile, American television actor Cat Deeley wore a bright pink shift, tan sandals, a leopard print clutch, a sleek ponytail and pink lip colour, while American Beauty actress Mena Suvari wore a little black dress with a pair of dramatic metallic gold shoes with black ribbon detailing on the back and carried a black box clutch bag. Suvari showed off a bit of skin and seemed hardly bothered with the fact she went through a messy divorce.

"I've never run into an ex who I have fallen back in love with. They all end up hating me. I just keep moving on. I don't like going back, I think that's unhealthy," Suvari said, when asked about the whole affair.

Suvari recently divorced Simone Sestito and, according to an E!Online report, Sestito asked for spousal support to the tune of $17,000 per month; he claimed Suvari made $750,000 a year while he had a negative balance in his accounts.

The star of the evening, however, was the Beverly Hills Hotel which, incidentally, was awarded the title of the city's "First Historic Landmark".

"We are truly grateful to the City of Beverly Hills for this Historic Landmark honour. We have always been inspired by the magic and beauty of our Beverly Hills location, and it has helped provide The Beverly Hills Hotel with an iconic backdrop. As we celebrate our 100th anniversary this year, we look forward to highlighting this new Historic Landmark designation with great pride and joy," Christopher Cowdray, chief executive officer of Dorchester Collection, said.
