Ja Rule Says Fat Joe ‘In Good Spirits’ Despite Underage Sex Lawsuit

Ja Rule says Fat Joe‘s “All the Way Up” amid his new legal headache … telling us the rapper’s in good spirits despite the claims of underage sex against him.

We caught up with Ja at Hot 97’s Summer Jam concert in New Jersey Friday … and, we had to ask him about how his friend and fellow New York-born rapper is doing after a man named Terrance Dixon filed a lawsuit against him this week.

ICYMI … Dixon — represented by attorney Tyrone A. Blackburn — is suing Joe and alleging Joe had a sexual relationship with multiple underage girls. Fat Joe’s attorney, Joe Tacopina, called the allegations “lies intended to damage his reputation and force a settlement through public pressure.”

Ja says he actually spoke to Fat Joe just a before he performed a tribute to Irv Gotti at the festival — and, he’s doing well despite everything going on.

In fact, JR admits he checked in to see if Joe could perform with him … but, the dude had his own show to do Friday and couldn’t make it.

Ja’s clearly got love for Fat Joe still … and, he’s not the only rapper offering him support during this trying time. 50 Cent posted earlier Saturday that claims about Joe trying to assassinate him — also made in the lawsuit — are total BS.

As we said … Ja was at the event to pay tribute to Irv Gotti who passed away in February after persistent health issues – and, he opens up about the emotional toll Irv’s death has taken on him.
