Teen Mom star Amber Portwood is often at the center of controversy and this weekend it revolved around jealousy of her baby daddy's new girlfriend. The situation came to a head when the two girls had it out over the phone, RadarOnline.com has exclusively learned.
"Gary and his new girl were hanging out on Friday night and Amber was late night texting him like she always does," a source close to the situation told RadarOnline.com.
"His date thought it was inappropriate the things Amber was saying so she called her and told her to quit trying to get him to hang out with her because he's moved on."
Portwood has also moved on with new boyfriend Clinton Yunker, but friends close to the reality TV star say she still holds out hope of getting back with Shirley.
"Amber was jealous to find out that Gary's been with other girls since the two of them broke up," the source said.
"Gary's new girlfriend is way prettier than Amber and it drives her crazy. She even asked her what someone as pretty as her would want with Gary."
According to the source, Portwood was so upset that she went over to Shirley's house and made him delete his new girlfriend's phone number from his cell phone.
"Gary really likes this new girl, but he was mad at her for telling Amber they were dating and stirring the pot because he knows how Amber can be," the source said.
"The whole thing was really weird because then all of a sudden Amber flipped the switch and started trying to befriend Gary's new girl, saying they should hang out and go find guys together."
As RadarOnline.com previously reported, Portwood was charged with domestic abuse following the airing of an episode where she hit Shirley and the Indiana Department of Child Protective Services temporarily removed daughter Leah from her home and placed the two-year-old with her father.
Leah has since been returned to Amber, 20, but remains under the supervision of DCS.
"Amber insisted on doing a three-way call with Gary and his new girl but got angry when she heard the way he was talking to the new girl because she said it was 'how he used to talk to me,'" the insider said.
