Glee Cast Celebrates Naya's Birthday in Vegas, Daily Mail Bitter they Weren't Invited

She plays a bitchy, backstabbing cheerleader on hit show Glee.

But Naya Rivera was not short of friends to help her toast her 24th birthday in Las Vegas this weekend.

And her fellow Glee clubbers certainly their hair down in sin city as they partied hard at The Bank Nightclub in the Bellagio hotel.

The group, which included star Cory Monteith, as well as Heather Morris, Harry Shum, Jenna Ushkowitz, Chord Overstreet, Kevin McHale and Amber Riley, looked like they'd been at the champagne as they sang Happy Birthday.

While she is in a supporting role onscreen, there was little doubt who was the leading lady at last night's birthday bash. And she played up to the occasion.

Naya, who plays Cheerio Santana, dazzled in a bronze sequinned dress and towering nude heels.

Posing inside the venue, the stunning brunette worked the tiny dress, which showed off her figure with its short hemline and plunging back.

The Glee students are not exactly known for their clean cut antics on the show, and the stars were not shy in letting loose in Las Vegas.

Amber Riley and Chord Overstreet appeared decidedly dishevelled at the party, as Jenna Ushkowitz and Heather Morris giggled and struggled to stay upright.

Meanwhile Kevin McHale blatantly ogled the attractive blonde waitress presenting Naya with her cake.

Cory Monteith appeared to miss out on the birthday cake, but may have been hitting up the casino, tweeting during the night: 'Vegas! Betting it all. Red or black?'

Missing from the festivities were Lea Michele, Chris Colfer and Dianna Agron.

Lea, who stars as good girl Rachel Barry, was held up with mysterious work commitments in Los Angeles.

The actress tweeted: 'It's very rare that u could have so much fun working on a weekend! Can't spill the beans yet as 2 what I was up 2 2day..but it was awesome! (sic)'

Mark Salling, who portrays bad boy Puck on the show, was also noticeably absent.

He and Naya were an item during the first season of the show, but broke up when heartthrob Mark said he was 'not in a committed or exclusive relationship.'

The pair were later forced to deny internet rumours that Rivera had egged and keyed his car when she found out he was seeing other women.

Despite his absence from her birthday, both have insisted they are the 'best of friends.'

The entire cast is riding high after taking home three awards at last week's Golden Globes, including Best Supporting actor gongs for Chris Colfer and Jane Lynch.

A sneak preview of a song from their highly anticipated Superbowl episode, to be aired after the game in the U.S. on February 6, has been released.

The gang sing a mash-up of Michael Jackson's Thriller and Yeah Yeah Yeah‘s Heads Will Roll.

'You can never re-create something as incredible as Thriller, and I don’t think we’re trying to,' Lea Michele recently told Entertainment Weekly. 'We’re making it our own.'

Betty White Celebrates 89th Birthday, Has No Plans to Retire

Betty White proves that age really is just a number. The 'Hot in Cleveland' star celebrated her 89th birthday at Le Cirque in NYC Tuesday evening and couldn't be happier with the turnout. The iconic star, whose sitcom returned for its second season Wednesday, confirmed she has no plans to retire like Regis Philbin. "If my job wasn't fun, I would have retired years ago," White told PopEater.

At the party, White caught up with new and old friends, munched on hors d'oeuvres and of course blew out the candles on her birthday cake. Although she wouldn't reveal her wish (it's bad luck), she's just thankful to have a job she loves and to be surrounded by supportive friends, family and co-stars. "I deeply appreciate everyone who came out tonight," she modestly told PopEater.

In honor of White's birthday, TVLand executives adopted an orphaned baby elephant in Africa and donated a "generous amount" to Morris Animal Foundation, one of White's favorite animal-rights charities. (They would not disclose the amount to PopEater.) White was overwhelmed by the gesture and told guests the donation would be "put to good use," and aid veterinary research that treats and cures animals on every continent and helps animals enjoy longer, healthier lives.

But the birthday surprises didn't stop there. Her 'Hot' co-stars, Valerie Bertinelli, Jane Leeves and Wendie Malick, joined White on stage and presented her with a video montage of birthday wishes from Taylor Swift, Kathy Griffin and Tina Fey (just to name a few.) The montage ended with a special surprise: Justin Bieber serenaded the star via video.

Her castmates gushed about White, adding she's still young at heart and spunky on set. "You look at her, and you don't think 89. She's nine. That's how she behaves," Bertinelli joked.

Other party guests included Sherri Shepherd, Hoda Kotb, Johnathan McClain, George Segal and Jack McBrayer.

White is best known for her television roles as Sue Ann Nivens on 'The Mary Tyler Moore Show' and Rose Nylund on 'The Golden Girls.' She currently stars as Elka Ostrovsky in the TV Land sitcom 'Hot in Cleveland.'

The spunky star has had quite a busy year. She appeared in an advertisement for Snickers during the 2010 Super Bowl XLIV. Then, a grassroots campaign on Facebook called 'Betty White to Host SNL (Please)' landed her a spot on the sketch comedy show. The 'Saturday Night Live' appearance made her, at age 88, the oldest person to host the show. The appearance earned her a 2010 Primetime Emmy Award for Outstanding Guest Actress in a Comedy Series, her seventh Emmy win overall.

According to White, she has a jam-packed 2011 ahead of herself. She plans to release two books while starring in 'Hot in Cleveland,' which returns for its second season on Jan. 19.
