Ultra-softs all the way as Kimi Raikkonen clocks the first time in Q1, a 1:14.296.
We're up and running with the first part of qualifying and there's no hanging about, 11 drivers are already on the track.
My word it is a veritable who's who of the celebrity world in Monaco. Ant and Dec are also in town.
Just minutes to go until qualifying gets under way.
You can listen to commentary online now and on BBC Radio 5 live imminently.
Here's a happy Jose Mourinho...
... here's a not-so-happy Mourinho.
Seriously, how can you not smile in the presence of the most happy person in sport?

At McLaren, there are hopes of getting both cars into the top 10. The team have been working on the problems Stoffel Vandoorne has been having this season, adding some rear downforce to the car and adjusting aspects of the set-up to help him with his ultra-late-braking style, which has been harming him so far. Obviously Fernando Alonso is not here as a benchmark, but the simulations say he can qualify eighth and Jenson Button 10th. Notwithstanding Button’s 15-place grid penalty for using too many engine parts, that would be a decent result for the team if the drivers can pull it off, and further confirmation progress is being made after Alonso’s seventh on the grid in Spain a fortnight ago.
If Lewis Hamilton takes pole position today it will be the 65th of his career, equaling Ayrton Senna's record.
This weekend marks the 30th anniversary of Ayrton Senna's first win in Monaco. He went on to triumph in the principality a further five times. No-one has won the race more than the Brazilian.
A statue of Senna is due to be unveiled at the Fairmont Hotel in Monaco.

Manchester United boss Jose Mourinho is in town. He's had lunch with Christian Horner and says he is a "huge" fan of Formula 1, although confesses he isn't an expert about it.

The sky is an untainted pastel blue, the boats are glistening in the harbour and the beautiful people are out in force. In the paddock, though, behind the white-fence walls, the talk is all about Ferrari and the remarkable pace they are showing. Sebastian Vettel is a dead cert for the win, people are already saying, and is a trend beginning to emerge at Mercedes? Monaco qualifying, one of the highlights of the season, is just around the corner.
Doesn't matter what Jenson Button does in qualifying because he will be starting from the back of the grid in tomorrow's race. He was hit by a 15-place grid penalty after an engine change.
Stoffel Vandoorne also has a grid penalty to be applied. He will drop three places from wherever he qualifies after being punished for colliding with Felipe Massa’s Williams in Spain.
Struggling at the back of the grid will seem like a world away for Fernando Alonso, who makes his Indy 500 debut tomorrow.
America has well and truly taken to the two-time F1 world champion.
You can read some words I wrote about his impact here.
We can confirm it is glorious in Monaco, Kayleigh (sorry!).
Kayleigh: Of course it's raining. Why am I not in glorious Monaco?!
Earlier, Nico Rosberg popped out of his Monaco home to catch up with some old friends and have a chat with Tom Clarkson.
Rosberg talks about life as a retired F1 world champion, his predictions for this season and whether his Mercedes replacement Valtteri Bottas can challenge for the title.
