Victoria Beckham has reportedly done a 'U-turn' on plans for a Spice Girls tour after the band reunited at her 50th birthday bash in London over the weekend. 

The group sent fans wild as they got together at the luxurious party held at Oswald's - and even did an impromptu performance on Stop in front of the star-studded crowd. 

Now insiders say Posh is weighing up the possibility of a reunion as her children; Brooklyn, 25, Romeo, 21, Cruz, 19, and Harper, 12, are older. 

'Victoria has finally realised that she really does miss the girls. The kids are all growing up and are independent in their own ways, she's not the 'mum' so much now,' a source told OK! Magazine. 

'Turning 50 and entering this new chapter has made her really appreciate her friendships with the girls and with Eva Longoria too. Having the girls at her party and spending time with them made her realise how much she loves and misses them all.

The group sent fans wild as they got together for the luxurious party held at Oswald's (pictured Geri Horner, Melanie Chisholm, Victoria, Emma Bunton and Mel B) 

'She has never really wanted to get back together because she's always said the Spice Girls are in the past, but now she's done a bit of a U-turn and is thinking "gosh I need my friends", a tour could happen now that she's had this realisation, Victoria is much more open to it than ever before.' 

MailOnline has contacted Spice Girls and Victoria's representatives for comment. 

It comes as Mel B broke her silence after it was reported she and her Spice Girls bandmate Geri Horner had a frosty reunion at Victoria's birthday bash.

The pair are thought to have had a tense exchange before keeping their distance from one another at the party, after Mel claimed in a recent interview that Geri has lied about her age.

Following the bash, Mel appears to have extended an olive branch, as she shared a group snap with her Spice Girls bandmates on Instagram.

She wrote: 'What an amazing girl power weekend with all my girls, i have soooo much love and respect for you ALL #friendshipneverends' (sic). 

The Sun claimed Geri, 51, and Mel B, 48, were feeling tense, after Mel claimed that Ginger Spice is not 51-years-old.

Despite travelling the world together in the band's heyday, Scary Spice claimed Geri always kept her passport close to her chest so she 'still doesn't know' how old she is. 

In the caption she noted that she has 'so much love and respect' for all of her Spice Girls bandmates

It comes after Mel B claimed in a recent interview that Geri has lied about her age for years, saying that Ginger Spice is not 51-years-old

And after the interview the pair are said to have kept a distance from each other at Victoria's party over the weekend - before Mel B reportedly tried to offer and olive branch.

A source told the publication: 'Mel tried to smooth things over with Geri at the party but it didn't go as planned. She was laughing it all off but Geri didn't seem interested in hearing what she had to say and wandered off.

'When it came to taking their group picture, Geri kept as far away from Mel as possible which was awkward to watch.

The group consisted of Victoria Beckham, Melanie Brown, Melanie Chisholm, Emma Bunton and Geri Horner (seen in 1995 in London)

Later in the night during the lavish festivities, all five of the Spice Girls came together to sing one of their hit tracks, Stop, for the star-studded guests - and again the pair were separated

'Geri wanted to be there to celebrate ­and have a good laugh with everyone, not talk to Mel about the embarrassing things she's said about her.'

Representatives for Mel B and Geri have been contacted by MailOnline for comment. 

After posing together as a five for a snap, later in the night the former band were seen singing their 1997 hit Stop together - in footage captured by David Beckham. But again the pair were at opposite ends of the line.

The former football player 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.

In the caption of the post, David penned to his followers, 'I mean come on x @victoriabeckham @melaniecmusic @officialmelb @emmaleebunton @gerihalliwellhorner,' followed by colourful heart emojis.

Victoria - who later gushed being reunited with the band was the 'best gift' - also shared the clip, writing 'best night ever! Happy Birthday to me! I love you all so much! #SpiceUpYourLife'. 

Social media users flocked to the comment section to share their thoughts over the reunion, with one typing, 'The moment the entire planet has been waiting for.' 

Another added, 'David you are the best social media manager out there, thank you for giving the people CONTENT.'
