Honey Boo Boo Cries After Rehearsal for 'Dancing with the Stars Jr.'

Honey Boo Boo is learning a hard lesson ... dancing can really suck.

The 12-year-old dissolved into tears after a rehearsal Saturday at CBS Studios in L.A.

All is not bad ... she's getting $50,000 just for signing to do the show, and the longer she competes the more money she'll pull in. If she makes it to episode 3 she'll get $10k, episode 5 she'll get another $15k, episode 7 she'll get $20k, episode 8 another $15k, and if she's in the finale she'll get another $20k.
