Now it's my turn to party: Rochelle Wiseman celebrates her 21st birthday just a day after boyfriend Marvin Humes' 25th

Rochelle Wiseman wasn't about to let her new boyfriend upstage her in the birthday party stakes.
Within 24 hours of celebrating Marvin Humes' quarter of a century, The Saturdays singer staged her own lavish party last night at the exclusive May Fair hotel.
Guests arrived wearing masquerade masks, while Rochelle wore a stunning silver and gem-studded dress with long train.

It's my party, and I'll wear what I want to: Not to be outshone, The Saturdays singer Rochelle Wiseman arrives at the May Fair hotel in a flowing silver dress for her 21st birthday bash

Watch it: But Rochelle was not pleased when someone stood on her train. Luckily a friend was quickly on hand to pull the offender back and help gather up the dress

She was joined by her girl bandmates Frankie Sandford, 21, Una Healy, 28, Mollie King, 22, and Vanessa White, 20, who all wore simple little black dresses in a effort not to outshine the birthday girl.
And it was all about Rochelle who served her guests cupcakes with her face on them.

The only glitches of the night were people accidentally standing on her flowing dress, and what appeared to be a parking ticket after leaving her white sports car in a restricted area of London's Mayfair.

But the singer was clearly enjoying her night of nights as she enjoyed bubbly with friends while cuddling up to Marvin on a couch.
The silver/grey colour scheme seems to be a favourite for Rochelle. She wore a sheer grey asymmetric top over a white mini dress with grey heels for Marvin's Friday night birthday drinks.

 Marvin, who celebrated his 25th birthday a night earlier at Alto in Soho, was also joined by fellow JLS singers Aston Merrygold and Ortise Williams.

Rochelle and Marvin made their relationship public just a few days ago.

No way, yes way! Now looking more incredulous, Una joins in animated conversation with Rochelle and Aston

The JLS star confessed to taking Rochelle to see adult stage show Avenue Q on one of their first dates, and described his new love as 'such a lovely girl'.
'I’m very fond of her. We’ve been on a couple of dates, and we’re going to see how it goes. She is really very lovely. That’s all I can say right now.
'The last one [date], we went to see the show Avenue Q and then for a nice meal at The Ivy. We get on really well together, but it's early days.'

Who's Dougie? After splitting from her long-term boyfriend, Frankie Sandford was pictured holding hands with a mystery man at the May Fair hotel. She was looking gorgeous in a simple strapless black dress

Daring: Amelle Berrabah from the Sugababes leaves little to the imagination in this backless dress

The couple were pictured having lunch at their London hotel yesterday following the big night at Alto, where entertainment at the party was provided by a troupe of Burlesque dancers.
Marvin even had time for shopping before his girlfriend's 21st as he clutched bags from Chanel and Selfridges before being picked up by Rochelle.
Meanwhile, Frankie appeared to be over her split with long-term boyfriend Dougie Poynter from pop punk band McFly.
She held hands with a mystery man as the pair helped celebrate Rochelle's milestone.
Other guests at Rochelle's birthday included Sugababes star Amelle Berrabah who dressed to impress in a backless dress with only a few pieces of string to cover her back.
