Off we go then. Ninety minutes of second practice and Daniil Kvyat, who only managed eight laps in FP1 one because of a fuel system issue, is straight out on to the circuit.

Lewis Hamilton is in rush. He is having a chat with Pharell who, you'd imagine, will have met him before when Hamilton has been on his travels.

“Alexander Rossi had a baptism of fire in first practice, crashing the Manor at Turn 18 close to the end of his first session of what will be his first grand prix, after being drafted in to replace Roberto Merhi. 

"The team have been working hard to repair the damage, and have needed to fit a new gearbox. They say they are ‘a few minutes from fire-up’. But a spokeswoman said they expected him to get out on track for the final half hour.”

Pharell has just popped into the Mercedes garage for a very brief chat with Nico Rosberg, who then heads off to get himself ready for second practice, which is about five minutes away from getting under way.

While Sebastian Vettel will be hoping to challenge Lewis Hamilton for victory this weekend, the two have also been battling for a very different title...least convincing waxwork lookalike.

The above recreations of the pair have been unveiled in Singapore this week. 

Not sure what to say really...Hamilton's hat looks good.

Thoughts?

"American Alexander Rossi had an unfortunate start to this career with Manor, who have drafted him in for five of the last seven races of the season in place of Spaniard Robert Merhi.  

"Rossi was doing well - with a fastest time of just 0.015secs off team-mate Will Stevens, who has driven the car all year - until he lost control and smashed into the barrier at Turn 18, doing considerable damage to the right-hand side of the car."

It has just gone 9.05pm in Singapore and cars will be rumbling out on to the circuit for second practice in 20 minutes. Radio commentary will be available just before it starts online & at the top of this page.

Hello and welcome to our coverage of second practice for the Singapore Grand Prix.

It was a Mercedes one-two in FP1 with Nico Rosberg topping the times ahead of Lewis Hamilton, but Red Bull's Daniel Ricciardo was not far off the pace, lapping within around three tenths of Rosberg.

Red Bull have won three of the last four races in Singapore, could they be the team to challenge Mercedes this weekend?

It was a mixed first day at the office for debutant Alexander Rossi.

After showing some good early pace in the Manor, the American, who has taken the race number 53 - the same as Herbie in the cheeky car caper films of the same name - smacked into a barrier late on, bringing out the red flag.

Will Herbie ride again in second practice?

So far so good for Nico Rosberg as he looks to cut into Lewis Hamilton's lead, but a long way to go yet.

Disappointment for debutant Alexander Rossi, though, with that late crash. Will Herbie ride again for FP2? We'll find out at 14:30 BST.

We are going to take a little break but will be back with live coverage from 14:00 BST. In the meantime, have a read of Andrew Benson's first practice report.

Such a shame for Alexander Rossi at the end, having been pretty much as fast as his Manor team-mate Will Stevens. Just 0.015 between them.

That, you would imagine, is that with barely a minute left of the session when Alexander Rossi crashed.
