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."

Lauren Plans Bachelorette Party In Las Vegas!

When it comes to planning bachelorette parties, Lauren Conrad knows how to work it. LC kicked off a Vegas weekend celebrating the bachelorette party of her cousin Cheryl with dinner at TAO Asian Bistro at The Venetian on Friday night.

The group of seven, including Conrad’s mother Kathy, sipped Lychee Martinis and feasted on specialties from the kitchen, including Satay Bass, Kung Pao Chicken and Vegetable Dumplings, finishing with a platter of desserts. After dinner they adjourned to a skybox in the nightclub for Champagne toasts, Grey Goose cocktails and dancing.

The party continued on Saturday as Conrad and friends took over a cabana at Tao Beach at The Venetian.

Despite the rain, LC continued the party and was overheard talking on the red carpet about her boyfriend Kyle Howard mentioning how everything was “great.” After Tao Beach the party continued as LC and her crew arrived at LAVO at The Palazzo and the final night of the bachelorette weekend. While they dined in a booth near the back of LAVO, the party was impossible to miss, with bride-to-be Cheryl donning items from the TAO Group’s Bachelorette Party Bag, including jewelry and accessories that glowed with a bright red light.

Silliness ensued as the night went on and they took over a VIP table on the dance floor. They danced all night to the sounds of DJ Eric DLux and toasted amid the screams of pure Vegas bachelorette bliss.
