Simone Biles proved yet again why she's the G.O.A.T this weekend ... 'cause the gymnastics superstar just took home her SEVENTH national title -- becoming the first woman to EVER win that many championships!!
The 24-year-old Olympic gold medalist straight-up dominated the competition at the US Gymnastics Championships in Texas ... winning first place by an incredible 4.7-point advantage.
Of course, Biles is known to be a trailblazer in the sport ... and lived up to her reputation when she nailed her signature "Biles II" move -- two flips and three twists BACKWARDS -- during her floor routine.
