Andrea Dovizioso has run out of fuel on his in-lap, and is getting a lift with Ben Spies back to the pits.
That's it then - Crutchlow has produced his best ever MotoGP qualifying to be second behind Jorge Lorenzo, with Pedrosa third,, then Spies, Dovizioso and Rossi on the second row.
Pedrosa is coming round for his final flying lap - he's half a second down in the second sector though.... yet he's up to third place! Spies is relegated to the second row - by just four thousandths of a second!
Ben Spies is out and trying to regain that second spot.
Crutchlow is on a great lap and might even challenge Lorenzo, but just loses it in the second sector a little - the slide costs him a couple of tenths, but he's back above Spies into second.
Dani Pedrosa comes back out looking to get this poor qualifying back on track - but he's made a big mistake on the first section and he's lost a second already. He'll stay out, take it easy on this lap and then go for it with the next.
You can give Lorenzo this pole already, but here comes Spies again... and he's bumped Crutchlow down to third! Crutchlow is back out though...
Spies dropped off in the final sector but still pulled himself up to third. Lorenzo's lap was incredible - a full third of a second quicker than the previous best ever, which was set by Rossi in 2009.
Jorge Lorenzo has nailed it! 1:55.799, and he's broken into the 1:55s at this circuit for the first time ever in MotoGP.
Lorenzo now two tenths up, Spies is also on a flier though and is right behind him within two hundredths!
Lorenzo is on another flying lap and has beaten his own pole time in the first sector.
Pedrosa comes back out onto the track and will have probably two more chances to nail a good one and get into the top three.
Lorenzo is the absolute class of the field so far toda, looking untouchable at the moment.
Dani Pedrosa is sitting fourth just now, with Ben Spues fifth and Valentino Rossi sixth.
We're into the final 10 minutes of the session here in Brno and Jorge Lorenzo is at the top of the timesheets, with Britain's Cal Crutchlow second and Andrea Dovizioso third as it stands.
Afternoon everyone - apologies for a few technical problems which have stopped our comments working until now.
