Farrah Abraham irked Amber Portwood with her Twitter comments last week.

The 23-year-old reality star tweeted a photo of her book cover for "My Teenage Dream Ended," which features herself with daughter Sophia. Abraham wrote, "Look@ covers as you collect them #ActionsSpeakLouder why aren't there more children on the covers #True Story @Mtv."

The post failed to sit well with "Teen Mom" co-star Amber Portwood, who interpreted the remark as a slight on her book, "Never Too Late." The cover image is a portrait of Portwood, and doesn't include her daughter, Leah.

"@F1abraham @MTV what does this mean?????" she responded Friday on Twitter. "I did it out of respect for my 6 year old who shouldn't be on the cover of a book talking about drugs and sex..love not hate."

Abraham and Portwood came to fame on MTV reality series "16 and Pregnant," and went on to star on "Teen Mom."

Abraham, who alienated herself from her co-stars with her 2013 sex tape and new gig as a stripper, recently shocked by revealing she will unexpectedly return for season five.
