The 21-year-old, who is currently dating Diversity star Sam Craske, is seen posing in a cherry shirt in the photo but eagle-eyed fans also spotted the sparkler on her engagement finger:
If she is indeed getting hitched, the Geordie singer will follow in the footsteps of her bandmate Perrie Edwards who recently became engaged to One Direction star Zayn Malik.
Zayn and Perrie sparked rumours that they were tying the knot after she was spotted wearing a diamond ring on her wedding finger at the premiere of One Direction's film, 'This Is Us'.
Her mum then confirmed the news, telling the Dorset Echo: "It's official. I'm over the moon. They are really in love."
