Nicki Minaj has proven that she is a loyal girlfriend after the "Anaconda" singer testified on boyfriend Meek Mill's behalf in the face of drug abuse allegations.

The rapper testified at Philadelphia court on Dec. 10 that her alleged fiancé was not lying when he claimed that he didn't take any illegal substance prior to the urine test.

"According to legal docs, during a drug test Meek handed the lab tech a specimen that turned out to be cold water," said TMZ. "Meek allegedly told the tech it looked that way because he had just consumed a lot of water, adding he was a bodybuilder and drank protein shakes that make his pee appear that way."

Meek Mill spent time in prison for eight months in 2009 after he was convicted of gun possession and drug dealing. Five years later, he spent another six months in prison after violating his probation.

Nicki Minaj then stood up to the judge and told the court that her boyfriend Meek Mill has changed so much since his earlier troubles.

"She's not going to be the one sleeping alone if he goes to jail. I am. He's not perfect, but I can't believe how much he's changed," she said, in a report from Associated Pres.

"He doesn't have a lot of structure," the rapper went on to add. "He can be irresponsible. Since I've come in his life, I think I've been working on that a little bit . . . He's just getting accustomed to being an adult."

"Nicki testified that Meek was telling the truth about his drug test, and said if she knew the protein shakes would make his urine appear like water, she would not have let him drink it," said TMZ. "And Nicki insisted to the judge, Meek doesn't do drugs and did not fake the test."

According to the report, the judge wasn't impressed with Nicki Minaj's testimony on behalf of boyfriend Meek Mill.
