'LHHA' Stevie J:Hey Judge, Joseline's a Lying Liar who Lies

Stevie J says Joseline Hernandez's life is all a lie -- right down to her age -- but the fibs weren't enough to convince a judge to issue a restraining order against her.

Stevie came out firing with juicy details about his "Love & Hip Hop: Atlanta" ex ... hoping they'd persuade a judge to extend a restraining order he got last month.

In his docs Stevie points out Joseline's real name is Shenellica Juneann Bettencourt ... she's 39 years old (not 29) ... isn't even from Puerto Rico ... might STILL be married to someone else ... and the baby in her belly probably isn't his.

The "newly discovered facts" fell flat ... because none of it had anything to do with the price of beans, or in this case granting a restraining order.
