It comes after Perrie Edwards revealed the touching note she received from Geri after giving the Spice Girls a shout out at the Brit Awards.

The 27 year old made history on Tuesday night as she and her Little Mix bandmates Leigh-Anne Pinnock, 29, and Jade Thirlwall, 28, became the first ever girlband to win the British Group award.

As part of their powerful speech, the Sweet Melody hitmakers dedicated their award to girl groups who had previously been nominated for the gong, but failed to pick it up.

Jade exclaimed: "This isn't just for us. It's for the Spice Girls, Sugababes, All Saints, Girls Aloud," whilst the audience erupted into cheers.

Perrie, who is expecting her first child with boyfriend Alex Oxlade-Chamberlain, showed her followers the handwritten note she received from Geri after the historic win.

The blonde beauty boasted how her house was "looking like a florist" as she shared a glimpse of the abundance of bouquets she had been sent after picking up the award.

She then posted a photo of the cards which were attached to the flowers, including a handwritten one from Ginger Spice herself.

The sweet note reads: "Dear Perrie, Congratulations and thank you for the shout out. Love, Geri xxx [Spice Girls]."

Perrie wrote atop the image: "Thank you so much @TheRealGeriHalliwell for the beautiful flowers!," also listing the companies who send her floral gifts.
