Bleary-eyed Eva Longoria can't stop giggling as she leaves best friend Victoria Beckham's star-studded 50th birthday bash

Eva Longoria couldn't stop giggling as she left Victoria Beckham's 50th birthday party in London on Saturday night.

The Spice Girl celebrated her milestone birthday over the weekend and her best friend Eva, 49, looked bleary-eyed but in good spirits as she left the star-studded bash.

The former Desperate Housewives star was seated in the back seat of a luxury vehicle as she headed home in the early hours and appeared to be wiping tears of laughter away.

At one point, Eva could be seen covering her face amid the laughing fit but her wide-eyed smile remained throughout.

The Flamin' Hot director had opted for a sleek black dress with a plunging neckline for the event and kept her smooth dark locks flowing free.

Featuring a low cut neckline, the dress was adorned with black lace and mesh panelling as the star flashed plenty of skin in the ensemble. 

Just before getting in the car, Eva was spotted  leaving Ozwald's private members club in Mayfair as she clutched a black purse and a goody bag from the fashion designer's glitzy do.   

Victoria celebrated the big 5-0 on Wednesday as she was showered with birthday wishes from across the world. 

Eva was among one of the first celebrities to send her birthday love to the Spice Girl as well as pals Kim Kardashian and former Spice Girls bandmates.

Eva, who revealed that she has sleepovers with Beckham 'all the time' last year, shared a sweet slideshow on Instagram and lengthy caption to honour her bestie.

'Happy birthday my beautiful sister @victoriabeckham!' she wrote. 'I'm so lucky to have you in my life. 

'Your friendship, loyalty, beauty and humor is endless! I wish everyone had a best friend like you.'

The evening was also memorable for the mini-reunion Victoria enjoyed with her the Spice Girls.

'It meant the world to Victoria that they were all there,' said a friend of the group reuniting at the party on Saturday. 'They were a huge part of her life and they shared so much together'; seen on their Return of the Spice Girls tour in 2007

The band  - which consists of Victoria,  Mel B, Melanie C, Emma Bunton and Geri Halliwell - were formed as Touch through an open audition in 1994 before going through a couple of lineup changes as hitting the charts as the Spice Girls with Wannabe two years later.

The Say You'll Be There hitmakers became the best-selling girl group of all time over their four-year run and reunited in 2007 for a world tour and again in 2012 for the ceremony closing of the Olympic games  but Victoria declined to join the band for their 2019 stadium shows. 

But on Saturday, all five of the Spice Girls came together to sing one of their hit tracks, Stop, for the star-studded guests - which was all caught on camera by Posh's husband David Beckham.

The former footballer could be seen with an excited smile on his face as the group showed off a few dance moves while singing along to the lyrics. Other partygoers also joined in on the fun during the special moment.
