Octomom -- I GOT A BOYFRIEND

Octomom -- the woman who said she's been celibate for the last 13 years ... and planned to stay that way until her kids reached 18 -- now has her very own BOYFRIEND ... and TMZ has the video evidence.

36-year-old Nadya Suleman arrived at LAX moments ago and her new boyfriend Frankie G picked her up outside. Frankie -- a 23-year-old amateur bodybuilder -- even gave her a peck on the lips when she arrived.

Sources tell us the couple's been dating about two months and it's getting serious -- but the best part ... when we asked Octo how they met ... the burgeoning porn star replied, "Through church." She wasn't kidding either.

It's all pretty crazy -- because back in March, Octomom told Closer magazine, "I’ve been celibate for 13 years and plan to remain so until the octuplets are 18." She insisted, “Men love me, but I will be celibate for the next 15 years."
