Gwen Stefani and Blake Shelton might be getting married soon – at least, according to this tradition.

The couple attended Blake's hairstylist Amanda Craig's wedding this weekend and the 46-year-old rocker caught the bouquet – well, kind of. According to a source, the flowers actually fell on the floor before The Voice judge picked them up.

"Amanda threw the bouquet, and it hit Blake in the head and fell on the floor," a guest told People. "Gwen picked it up!"

The couple went public with their relationship just two months ago and things seem to be heating up quickly. They've been photographed showing major PDA and have exchanged flirty messages on social media, as well.

Plus, In Touch Weekly has reported that Gwen is pregnant with the 39-year-old's baby.

Maybe wedding bells aren't too far off for the duo!
