We're staying abreast of the latest developments in Teen Mom Jenelle Evans' life, and surprise! Today the frequent Tweeter wrote, "I'm the luckiest girl in the world to have @gary_head in my life." Along with the homage to her boyfriend, Evans tweeted a picture of a ring -- with a miniscule diamond! Yes, it looks like Head raided the gumball machine to make an honest woman out of the sometime-jailbird and often birdbrain, who most recently made headlines with her breast augmentation. Coincidentally, Head was nowhere to be found during her recovery; in fact, certified dirtbag and ex Kieffer Delp was the one to help her take those before-and-after pictures of the ta-tas -- and publish them online after the deed was done. The 21-year-old reports that even her mom, Barbara, with whom Evans has had an explosive relationship with in the past, approves of the impending nuptials.
