She appeared to hint that she could be engaged to beau Alex Oxlade-Chamberlain earlier this week after saying she'll remember his surname 'once it's hers'.
And Perrie Edwards only fuelled the rumours even more on Wednesday night after she hid her ring finger at Little Mix's PrettyLittleThing launch at Aynhoe Park House in Banbury.
The singer, 26, wore an oversized white bardot shirt dress which had long sleeves that hid her hands and fingers.
Perrie cinched in her waist with a metallic mandala print corset and teamed it with matching thigh-high heeled boots, a headband and a mini handbag.
The star also went on to leave the event early with her fans speculating that it could be her anniversary with Alex after first sparking romance rumours in November 2016.
Tulisa, who mentored Little Mix as a judge on the 2011 series of The X Factor, shared a picture of herself with Jesy Nelson, Leigh-Anne Pinnock and Jesy Nelson, revealing that Perrie had an 'early night.
Doing their signature arm pose in the snap, the former N-Dubz star, 31, captioned the photo: '@littlemix @jesynelson @jadethirlwall @leighannepinnock .... @perrieedwards had an early night we forgive you ❤️ #muffins #loveualways #reunited.'
Fans were quick to comment on Tulisa's post claiming that Perrie had an early night because it was her anniversary with Alex.
One person said: '"Perrie had an early night" we all know why [crying laughing and heart]'
While a different user added: '"Perrie had a early night" cus it's her and Alex adversary?' followed by eyes emoji.
MailOnline has contacted Perrie's representative for comment.
Perrie's appearance comes after she sparked speculation that wedding bells could be on the horizon after her boyfriend Alex pointed out a hilarious blunder.
The singer took to Instagram Stories to praise her footballer beau, both 26, earlier this week after he was named Man Of The Match for scoring the winning goal in Liverpool's clash against Genk.
After Alex sent Perrie a message telling her that his surname was spelt incorrectly, the star playfully wrote that it would be easier to spell 'once it's her second name.'
In her first post, Perrie celebrated Alex's goal for Liverpool with a celebratory snap, along with the caption: 'You to me are everything my Alex Oxlade-Chamberlaine OH BABY OH BABEHHH.'
One of the star's followers were quick to point out that Alex's surname was spelt incorrectly, writing: 'I love you and him but you should be able to spell his love, up them reds.'
Perrie took the blunder in good humour, writing: 'F**k sakes! My bad. Thank you Jack.'
Alex himself also couldn't resist poking fun at his girlfriend, posting her snap with the caption: '@perrieedwards spell my name right at least will ya.'
Perrie then shared a snap of a message from Alex poking fun at the mistake, reading: 'Also I cannot believe you spelt my name wrong on your story,' which she captioned: 'I hate myself.'
It was Perrie's next post that sparked the speculation that an engagement could be in horizon, as she wrote: 'It'll be way easier to spell when it's my second name and I have to write it all the time.'
Perrie is no stranger to supporting Alex in his sporting success, and previously joined him in Madrid when Liverpool won the UEFA Champions League in June.
Their relationship is definitely heating up, as the pair recently moved in together earlier this year.
The Woman Like Me singer said on BBC Radio One last year: 'We had date night, it was competitive, it got out of hand.
'I swear to God I thought he was going to dump me - and I thought I was going to dump him. If you think I'm competitive, you should meet him.'
Perrie and first sparked rumours she was dating Alex in November 2016, following a brief romance with actor Luke Pasqualino.
The star was previously engaged to One Direction singer Zayn Malik, but they split in 2015 after three years together.
Perrie has previously stated that she definitely wants to marry the sports star one day. She told Metro: 'I hear a violinist and I'm like, That's going in my wedding! I love strings, the whole idea of marriage ... the day and the dress.
'I'm a hopeless romantic but, at the same time, I'm career-driven first. I know marriage is lovely and cute, but I'd rather just be with Alex for the rest of my life if I had to pick.'
