An Instagram photo of her daughter Aubree posing with her ex's on-again off-again girlfriend left Chelsea irritated on tonight's episode of "Teen Mom 2."

Despite the young mother's differences with her four-year-old's dad Adam -- and her feelings about his other baby mama Taylor -- she's tried to keep her frustrations about the duo's relationship with little Aubree to herself. But that silence ended when she discovered Taylor's snapshot on social media.

"Why are you posting selfies with my kid when you're not with the dad anymore and we're not friends?" Chelsea pondered with her friend Chesley Grace before contemplating Taylor's motives -- and whether or not the pic was posted in order to seek attention and cling to her past with Adam.

Her immediate reaction: firing off a blunt text to Taylor which read, "You are seriously crazy. Stop posting pics of my daughter."

Taylor sent back a long reply, stating Aubree asked to see her, that she's been in the young girl's life for the past three-and-a-half years (a statement Chelsea debunked given Aubree's age) and that Aubree should be able to spend time with her sister Paislee. Chelsea tried to make it clear that her message had nothing to do with Taylor's relationship with Aubree, but that she merely wanted her to refrain from sharing the snapshots.

Later, Adam made a statement by inviting Taylor to Aubree's softball game. In response, Chelsea chose to focus her attention on her mini-me playing on the field -- and ignore the others. "I don't know what he does, or who he does," Chelsea told her dad Randy when he asked about Adam's current status with Taylor.

Randy provided his daughter with some important insight -- that most families deal with this type of co-parenting -- but Chelsea's initial response proved that Taylor's connection with Aubree is a sensitive issue. While Chelsea was clearly agitated by the photograph, did she overreact by sending Taylor the text message? Or were her actions, as well as her tone with Taylor, warranted?
