Does AnnaLynne McCord Have A New Man?

AnnaLynne McCord looks like she may have snagged herself a new man.

The 90210 star was far from shy with model Aaron O'Connell Saturday while hosting a party at Lavo Las Vegas, walking into the club hand in hand and never leaving each other's sides.

Inside, McCord and O'Connell were seen flirting with each other in their VIP section, taking pictures together on their personal cameras and drinking Veuve Clicquot champagne. Later, she was spotted sitting on his lap.

"They were all over each other," an observer tells PEOPLE. "There were definitely not trying to hide anything. They were dancing all over each other and didn't separate."

Dressed as the White Queen from Alice in Wonderland, McCord could also be seen wearing O'Connell's hat, an accessory to his pilot costume.

Earlier this month, McCord, who told Ryan Seacrest in September she was "very with" Twilight hunk Kelan Lutz, and O'Connell were at a benefit in Los Angeles for The Homes That Hollywood Built, a benefit for the St. Bernard Project which helps supply housing for those who lost homes in Hurricane Katrina.

A rep for McCord did not immediately respond for a request for comment.

Annalynne McCord Hosting LAVO Las Vegas

Doing her best to create the perfect party atmosphere, AnnaLynne McCord played hostess at LAVO Las Vegas on Saturday night (October 30).

Joined by sister Angel, the "90210" hottie downed champagne as she tossed on a pilot's cap while fronting Veuve Clicquot's annual Yelloween bash.

Aside from Halloween party efforts, AnnaLynne recently chatted about what makes her feel sexy with People magazine at the 50 & Fabulous: Celebrating 50 Years of Women's Advances Since the Pill gala.

The 23-year-old dished, "When I want to feel sexy I like to dance, even if I'm at home by myself in my knee-high socks sliding there like Risky Business ... My sisters and I, if one of us starts, we're all there in front of the mirror, dancing and it's just obnoxious. I feel sexy when I do that."

STYLE POLL: Lo Bosworth v. Amber Lancaster

Lo Bosworth and Amber Lancaster have a lot in common — not only have these gorgeous gals both starred in popular MTV shows, they share the same taste when it comes to style!

Lo, former reality star from The Hills, celebrated the launch of her new lifestyle blog TheLoDown.com at Lavo in Las Vegas on Sept. 3, and opted for the French Connection Dance Daisy Dress. She paired it with minimal accessories, including a turquoise Chanel purse.

Meanwhile, The Hard Times of RJ Berger star Amber wore the exact same dress earlier this summer, to the French Connection Fall 2010 Collection Celebration at the Soho House in Los Angeles on Aug. 17. She also kept the accessories to a bare minimum, opting for a few bracelets, and nude pumps, which were very similar to Lo’s.

I really like that both girls kept it simple because it makes the dress stand out more. Though I must say, I think Amber definitely wins this battle! It fits her flawlessly, and she just looks like she’s having more fun! Either way, Lo and Amber were smart to wear this adorable (and affordable!) number.
