Marvin Humes rang in his 40th birthday with a lavish party at The Savoy H๏τel with a huge A-list guest list on Saturday night. 

The JLS singer celebrated the landmark birthday with wife Rochelle Humes and their three children Alaia-Mai, 11, Valentina, seven, and three-year-old son Blake at a black tie bash at the 5-star London H๏τel. 

And on the guest lists, Marvin’s newly single close I’m A Celebrity pal Sam Thompson and Pete Wicks were spotted downing cocktail and flirting with women outside the venue. 

Sam, 32, whose ex Zara McDermott was spotted for the first time since her relationship with Louis Tomlinson, looked to be back to his usual self following the heartbreaking split.

The Made In Chelsea alum dressed to impress in a handsome blue suit with a matching shirt as he flashed a smile as he chatted away to two mystery women, both wearing black dresses, outside the swanky H๏τel.

In pictures obtained by The Sun, Sam placed a tender hand on one of the women’s arms and was then seen cuddling a female party-goer in a pink dress as they stood in the foyer, before the pair headed out for a cigarette.

She is now thought to be dating One Direction star Louis after the pair were spotted enjoying a romantic evening overnight in SusSєx. 

However, after being together for five years, Zara and Sam have a lot of mutual friends, who are now reportedly ‘stuck in the middle’ amid the drama. 

A source told The Sun: ‘It’s really hard as the friendship groups were combined for five years and everyone was so supportive.

‘But now they’ve been torn apart and people are having to take sides. Some people have chosen Sam, others have chosen Zara – and some people are stuck in the middle.’

Louise was cynical about Zara but did warm up to her. Pete was always close to Zara, so the split is hard for him too.’

MailOnline has contacted representatives for Zara, Sam, Pete and Louise for comment. 

Zara and Pete also have a close friendship, with Pete previusly admitting it was Zara who pushed him to do Strictly Come Dancing.

She previously said of the friendship: ‘The three of us have a very odd relationship, but it’s very amazing. 

‘He’s literally my brother, my best friend. He’s Sam’s brother and his best friend. Me and Sam are together, so, I love them both very much in different ways.

‘It’s a strange dysfunctional family. It works so well because we are all so different, the three of us, that we… just anything that any of us is faced with, like we’re all there for each other. It’s so lovely.

It comes as Sam and his ex Zara’s celebrity friends began ‘taking sides’ after she embarked on a new romance with Louis Tomlinson

‘And I know it sounds a bit weird to be best friends with your boyfriend’s best friend – the whole trio.’ 

Zara and Pete also made a slew of hilarious TikToks as they spent time together while Sam was in Australia on I’m A Celeb. 

Meanwhile, one fan took to Louise’s Instagram comments to address how she will move forward with her friendship with Zara, writing: ‘Hope you don’t just drop Zara’.

Louise appeared to make a defiant statement about her friendship with Zara by liking the comment.

Sam and Zara regularly made fun TikTok videos with Louise and her partner Ryan Libbey and the group also travelled together on lavish holidays.

And last month, Louise and Sam took to the BRIT Awards red carpet together, narrowly missing an awkward run-in with ex Zara.
