The 13th seed scraped into the second round, clinching a 7-6(8), 4-6, 7-5 win on her fifth match point after producing groans from the Chatrier crowd when she double-faulted on her first.
On a day when heavy rain shortened the programme, the twitchy Bartoli, full of ticks and eccentric mannerisms, could have been accused of hogging the stage as she made men's world number one Novak Djokovic wait for his grand entrance.
In the end, however, the crowd did not care as the French number one battled back from 5-3 down in the decider to move through to round two, saving two match points in the process.
Bartoli's victory actually took most of the afternoon because after a rain-delayed start she moved a set and a break ahead before being forced off by yet more showers.
Having started at lunchtime, it was around 18:30 local time when Bartoli finally left the stage.
There was no doubting the entertainment value though.
Going through her full repertoire of baseline shadow boxing in between points, swishing her racket at an invisible ball, Bartoli cuts a comical figure at times.
Occasionally she glared towards her father and coach Walter, whom she banished from the crowd during one of her Wimbledon matches in 2011, at other times she punched the air.
All the expended energy looked to have been futile though when Belarussian Govortsova began pinning Bartoli into the corners with some heavy hitting, usually accompanied by loud moans and grunts.
At 5-3, 40-15 Govortsova was poised for victory but a nervy forehand into the net offered Bartoli a lifeline and she saved a second match point with a thumping winner.
Having broken her opponent to lead 6-5 she then took 10 minutes to hold serve, finally edging through when Govortsova framed a service return into the tramlines.
