Everything that surrounds myself, I don't really know a lot of it.
It was world No 60 Bouchard's first ever victory over five-time Grand Slam victor Sharapova, whom she believes should be banned from tennis for life.
Sharapova upped her intensity once more to break back to 15, but a marathon 18-point 11th game tipped the balance of the first set Bouchard's way when Sharapova fired long and Bouchard served it out 7-5.
Bouchard did her talking on the court last night, defeating Sharapova 7-5 2-6 6-4 in a near three-hour epic on the Madrid clay.
"She said: 'Well played, '" Bouchard replied when asked what words were exchanged at the net.
Earlier, top-seeded Angelique Kerber defeated Katerina Siniakova of the Czech Republic 6-2, 1-6, 7-5 to advance and regain the world No. 1 ranking.
"I definitely had some extra motivation going into today, Obviously I had never beaten her before and then there were other circumstances", she told a news conference.
Sharapova broke back immediately but then dropped another service game to allow Bouchard to serve out for the match.
Sharapova said she is not being affected by the off-the-court controversy involving her return to tennis.
"Sharapova is now marooned on 250 points with one tournament left before the entry "cut off" date for Wimbledon".

You can't afford any more tough streaks, I know that. "That's what you're seeing from everybody that's getting a chance to play". Bauer has been largely ineffective and his problems have led to a 2-3 record with a high 7.67 ERA over five outings.
The world number 60 admitted she was extra motivated to face her former idol and it showed with signs of the form she has lost over the past few years since reaching the Wimbledon final in 2014 in a bruising near 3-hour contest.
That would mitigate her reliability on wild cards that a lot of her fellow tour players have opposed. If everything affects you on and off the court, I think that would be a really challenging position to be in.
The two exchanged a frosty handshake at the end of a thrilling almost three-hour long encounter as Bouchard registered just her second WTA Tour win since the Australian Open in January.
Sharapova won again to move into the semi-finals after beating Anett Kontaveit of Estonia 6-3, 6-4.
It was their first meeting since Bouchard called Sharapova a cheater and said she should have been banned for life from the sport after testing positive for meldonium.
Bouchard converted her second match point with a searing crosscourt forehand victor to close the books on her biggest win of the season.
Bouchard's win is all the more remarkable because she hadn't managed to win a match in three-and-a-half months before she entered Madrid.
Neither player was prepared to give ground in the decider as Sharapova survived five break points in the fifth game. "So I want to at least take advantage of that, just go for it, play good tennis, build on this, and enjoy it, kind of just show what I can do". "All the things that hopefully I can improve from today's match and take it against her".
Second-seeded Karolina Pliskova was upset in the second round, falling to Anastasija Sevastova of Latvia 6-3, 6-3.
