In bizarre news, Jenelle Evans announced on Twitter today that she and on/off again boyfriend, Gary Head, are engaged. The reality star posted a snapshot of the ring with the phrase, “I’m the luckiest girl in the world to have @gary_head in my life.”

Jenelle followers may find this confusing as she was dating new boyfriend Keiffer Delp only a short while ago. He reportedly escorted her to the surgeon's office when she got her new breast implants.
