Pop star Britney Spears has been sending handwritten notes to her biggest fans inviting them to her Las Vegas “Piece of Me” concert.

Britney Spears has reached out to her most supportive fans and offered them a complimentary pair of tickets to see her in action next year, reported Female First.

One fan called Cody took to Instagram to share his letter from Spears.

“Cody, I wanted to send you a little note and say thank you for all your support over the years! You always make me and the people around you smile,” the letter read.

“That is such a gift! You know what would really make me smile? Seeing you in Vegas next year! You let me know what date and I’ll save you 2 tickets (sic)!” it continued.

Alongside a picture of the note Cody posted, “I JUST GOT A LETTER FROM BRITNEY SPEARS. THANK YOU SO MUCH BRITNEY. I LOVE YOU (sic)”

Another social media user named Alycia, who uses the handle @fitlikebritney and documents her weight loss on the photo-sharing app, shared a screenshot of her invitation and admitted the personal note was “beyond her wildest dreams”.

She said, “Today something beyond unexpected and beyond my wildest dreams happened. I received a handwritten card from Britney herself. The moment I opened it and saw my name, I immediately recognized the handwriting and burst into tears.(sic)”

In her note to her fan, the “Womanizer” hitmaker praised her “hard work and dedication” and told Alycia she wanted to “reward” her.

“Alycia, Your hard work and dedication are so inspiring – you look amazing! You are a beautiful person inside and out. Would love for you to reward yourself and come to one of my shows in Vegas in 2016! Let me know what day, and I’ll make sure you get a pair of tickets (sic),” she wrote.
