Usher and his girlfriend seem to be headed toward one of the wedding chapels in Vegas -- at least that's what these legal filings suggest ... which gives 'em a green light to get hitched.
The singer and his longtime partner, Jennifer Goicoechea, obtained a marriage license on Feb. 8 in Clark County -- this according to court records obtained by TMZ. Their marriage certificate is not yet filed ... so for now, it seems they haven't said "I do" yet.
Unclear if Usher and Jenn are actually gonna get married tonight -- considering he just had a huge Super Bowl Halftime show an hour ago .
