Singer Jordin Sparks was given a shock on Valentine's Day (14Feb14) when her boyfriend Jason Derulo surprised her with 10,000 red roses.

Sparks shared her partner's romantic gesture with fans by posting a picture of herself standing in a room packed full of flowers, writing in a post on Twitter.com, "Completely overwhelmed by 10,000 roses today from, my love, Jason DeRulo. They're so beautiful! Omg (oh my God)..."

There were too many flowers for her to keep, so Sparks shared them out with staff at a hotel in Los Angeles where the couple spent the most romantic day of the year.

She adds, "(I) took a few vases home but gave the rest of the roses to everyone at The Redbury hotel! Happy Valentine's all around!"

DeRulo added, "10,000 roses fill this suite! I only wish I could've fit (sic) 10,000 more in here! Valentine's every day!... I'm glad we were able to give the excess of the 10,000 roses away after the surprise. Spread the love ya'll (sic)."
