Amber Portwood Attacks, Threatens Gary Shirley's Girlfriend Again!

Teen Mom star Amber Portwood may not be pregnant, but she is back to her old ways in another respect - attacking her ex and his new girlfriend!
Portwood physically attacked Gary Shirley for the second time this month, threatening his current girlfriend Ashley in the process Tuesday night.
Amber had bonded with Ashley after she thought her relationship with Leah's father had cooled. But when she learned it hadn't, girl went OFF.

UNHAPPY FAMILY: Tranquil, ordinary moments like this are few.

"Amber said Gary was sending her flowers and texting her, saying he hadn't been talking to Ashley," a source said, but once they got to Gary's house?
"Amber hit Gary for trying to play both of them."
The night soon turned even uglier when Amber, already facing felony battery charges for a prior, televised attack, realized he was still dating Ashley.
"When Amber learned that Gary was still communicating with Ashley, she got in Ashley's face like she was going to hit her," the source added.
