Kailyn Lowry and her alleged girlfriend Dominique Potter have split. According to a new report, the "Teen Mom 2" star and mother of three has found herself single once again after her months-long romance with Potter came to an end.

"[Kailyn Lowry] is single," an insider told Radar Online on January 8. According to the report, the "Teen Mom 2" star decided that after months of dating her girlfriend, she no longer wanted to be involved in a committed relationship. As for what went wrong between them, the source said that Lowry still hasn't gotten over her troubled relationship with Chris Lopez, the father of her youngest son Lux Russell [VIDEO].

Lowry shares one child with Lopez and also has two other kids.

Kailyn Lowry is mom to four-year-old Lincoln, who she shares with her former husband Javi Marroquin, who is now dating her co-star, Briana DeJesus, and to seven-year-old Isaac, whose father is Jo Rivera.

Are Kailyn Lowry and rumored girlfriend Dominique Potter still friends?

The Radar Online insider said that while Lowry has decided to focus solely on her three kids, she and Dominique Potter have remained friends -- just as they were before their romance began. As fans may recall, Lowry first confirmed she was dating another woman in November and, at the time, she noted that she and her then-girlfriend had been friends for about one year before their romance began.

Although the "Teen Mom 2" star never actually confirmed that Dominique Potter was her girlfriend, the alleged couple were seen together on numerous occasions and even appeared to film scenes for the MTV reality series together.

In one particular photo shared on social media, the women appeared to be holding hands while seated in a car together.
