"I'm the luckiest girl in the world to have Gary Head in my life," Jenelle recently tweeted, along with a photo of her engagement ring.

"Gary asked her to marry him last month," a source confirms to Us Weekly. "She wasn't certain about Gary and didn't want things to be that serious between them."

Reportedly, she changed her tune after Gary took care of her while she was recovering from her boob job earlier this month.

Though their relationship has been notoriously rocky ("I'm very depressed. Me and Gary broke up for good," she tweeted April 8), anybody has to be better than Kieffer right?

Though perhaps we shouldn't count out Kieffer just yet -- apparently, the two were back together just a few weeks ago.
