The 'Talk Dirty' singer went one better than Kanye West - who gifted his wife-to-be, Kim Kardashian, ''a thousand'' roses - by filling a suite at the Redbury Hotel in Los Angeles with the bright red flowers.
He wrote on Twitter: ''10,000 roses fill this suite! I only wish I could've fit 10,000 more in here! (sic)''
Jordin, 24, was amazed by the lavish gift when her fiance surprised her with them.
She tweeted: ''Completely overwhelmed by 10,000 roses today from, my love, @jasonderulo. They're so beautiful! Omg.... (sic).''
Jordin then posted another photo of them together with one of the bunches, adding: ''Preeeetty sure my face says it all. I love you babe!''
Romantic Jason, also 24, also played matchmaker on the romantic day on Friday (14.02.14), as a member of his audience proposed to his girlfriend while he performed his track 'Marry You' at the Nokia Theatre in Los Angeles, as part of a Valentine's Day concert.
He also shared the flowers he and Jordin aren't able to keep with other lovers, tweeting: ''Happy Valentines! I'm glad we were able to give the excess of the 10,000 roses away after the surprise. Spread the love ya'll.''
Gendry has been living under Cersei Lannister's nose for quite some time now.
The director would love to take the films in a different direction.
He'll be performing a new residency at an intimate theatre.
