Katy Perry and Orlando Bloom are tying the knot!

It's an exciting day for Katy Perry and Orlando Bloom, who confirmed on Valentine's Day they're engaged after three years of dating on and off. The "Part of me" hitmaker on Friday took to Instagram to share the news, reports dailymail.co.uk.

Perry posted a close-up image of the pair surrounded by heart-shaped balloons as she showed off her flower-shaped diamond ring, which features a colorful pink jewel in the centre, reported People magazine."Full bloom," she captioned the picture in an apparent play on her fiancé's last name. Bloom shared the same image and captioned it, "Lifetimes".

"A shallow person will have only shallow relationships," Bloom wrote on Instagram the day of their engagement. "Real love is not one person clinging to another, it can only be fostered between two strong people secure in their individuality. Antoine de Saint-Exupery, author of The Little Prince wrote in a work called Wind, Sand and Stars, 'Love is not two people gazing at each other, but two people looking ahead together in the same direction.'"Katy's mother Mary Hudson also shared images of the emotional proposal on Facebook, with caption: "Look who got engaged last night."
