Jenelle Evans made good on her promise to get a boob job.

The "Teen Mom 2" star, 20, got breast implants Wednesday, according to her official Twitter account. "Now I'm at home recovering with [my best friend] Allison Elise as my nurse."

In March, a source told Us Weekly that Evans wanted "to go a size or two higher." Another Evans insider said "she's wanted it for a long time."

Evans, who split with boyfriend Gary Head in early April, is relying on her on-again beau Kieffer Delp during her recovery. "Thank you so much for being there for me today and everyday," she told him via Twitter. "You are always there when I need the most!"

The MTV reality star and mom to son Jace, 2, said her new boobs are the "perfect size."

Evans follows in the footsteps of "Teen Mom" co-star Farrah Abraham, who went from an A cup to a C cup in early 2011.

"I thought I lost 'boobage' from having a baby," aspiring model Abraham told Us last year. "It was a challenging time, [but] it's helped my confidence and [made me] feel more like a woman."
