As a global pop star, she's more used to filling stadiums than sitting in them.
So Jessie J can perhaps be forgiven for getting the dress code wrong when she supported Tottenham Hotspur alongside her father Stephen as the team took on Everton at White Hart Lane on Sunday.
While Jessie looked in good spirits as cameras caught her cheering on the team, the singer admitted she had committed something of a faux pas as she arrived wearing a red dress.
Come on you Spurs! Jessie J goes to show support for Tottenham Hotspur's big game against Everton
Error: Jessie wore a red dress as she headed to the game, before realising her faux pas
The 25-year-old was forced to quickly purchase some souvenir strip in the team's colours of navy and white in a bid to conceal her error.
She tweeted: 'I was invited by Spurs to see the game today as my Dad is a huge fan! I wore a RED dress #fail! (No other reason other than I love red) so when I arrive to the chairmans dinner...I was like a voice chair in a room full of people wearing grey and navy!
'So I bought a hoody and a scarf to look less *red* meanwhile my Dad is telling everyone "I should of told her when is saw her in red" lmao!' (sic)
Like father, like daughter: The Voice coach brought along her dad Stephen, who is a big Spurs fan
Keeping her eye on the ball: Jessie pulled a variety of facial expressions as she watched the game
Dressed in a grey marl Spurs hoodie and a navy and white striped football scarf, her last minute purchases helped her to look the part.
When she realised she had been spotted on television, she added: 'Then I'm on tv getting proper involved! Oh how I must laugh at myself. Never a quiet family day anymore... Lol!
'Hoody and scarf styley!! Love my Dad so much making me laugh!! had a great time! Yes #spurs' (sic)
Jessie, real name Jessica Cornish, grew up in Seven Kings and Romford, only a couple of miles away.
Nice view! The Do It Like A Dude singer tweeted this picture of the pitch to her followers
She later took a picture of the playing field with the caption: 'Loving the view! #spurs with Dad!! Caaaame on youuu Spurs!!' (sic)
Defending
her corner: Gail Porter defending Jessie's charitable head shave, but
denied that she thought the star was 'brave' for doing so
However,
not even her superstar appearance, or even the support from former
Spurs player Paul Gasgoigne, who was also spotted at the game, could
push Spurs to victory, as they eventually settled for a 2-2 draw against
the Liverpool side.Jessie's hair has grown since she had her head shaved to raise money for Comic Relief just a few weeks ago.
Her charitable act helped to raise around £500,000 and many people have leapt to her praise.
However, not everyone feels the same way. In Sunday's issue of the Scottish Sun, Gail Porter explained why she thought Jessie's actions weren't brave.
Gail, whose mother died of cancer, said: 'She (Jessie J) did a great thing. She raised a load of money, she made bald look cool... but brave?
'That is a word dedicated to my mum and so many others like her.'
The columnist has suffered from alopecia since 2005, and although her hair was starting to grow back in 2010, it has since disappeared again.
However, Gail also defended Jessie from negative twitter comments that have circulated the star, with some calling the head shave a mere publicity stunt, with Gail instead calling it a 'very generous and honourable gesture'.
