Casper Smart wants him and Jennifer Lopez to get matching tattoos.
The 25-year-old dancer is desperate to tie the knot with the three times married star but instead of buying her a ring, he suggested they get inkings affirming their commitment on their ring fingers, to Jennifer's horror.
A source told America's Star magazine: ''When he presented her with that idea Jennifer could barely control her laughter. The poor guy knows he's up against four previous engagements and three marriages so it's impossible for him to do something special that he can afford.''
Jennifer - who started dating Casper after splitting from third husband Marc Anthony, the father of her four-year-old twins Max and Emme - recently admitted she is not ready to tie the knot with her partner, though they are very happy together.
She said: ''[Usually I'm like] Where is it going? Are we getting married? But now I'm like, maybe it's OK to just be in the moment. Maybe it's OK to enjoy this for right now. Who knows where it's going? There's love here. Relax.''
