Sunday's 2017 Formula 1 VTB Russian Grand Prix was full of action on track, but there was also plenty going on behind the scenes in the build-up to the race weekend. Here's our round-up of just a few of the highlights...
Oh, the glamour...
What does a jet-setting F1 driver do in his spare time between Grands Prix? Assemble flat-pack wardrobes, of course - at least if you are Haas's Kevin Magnussen.
That's more like it!
While Kevin was at home wrestling with DIY, Mr and Mrs Massa were soaking up the rays, watching tennis legend Rafael Nadal wrap up the Monte-Carlo Masters.
Earning Brown-ie points with Alonso
Fernando Alonso makes sures McLaren boss Zak Brown keeps his word as they head Stateside for Indy 500 preparations.
It's a big one!
A former F1 driver - Alex Rossi - won it last year. Could a current F1 driver win it this year?
When Russian dolls are as big as these matryoshka, you have to wonder just how many more are inside.
The easy way to embarrass your driver?
Tweet a few pictures from his 'younger days'. Toro Rosso's local hero Daniil Kvyat was the 'victim'.
A clean sweep for Kvyat
Toro Rosso's Daniil Kvyat makes full use of Sochi's winter Olympics facilities, as he gets to brush up on his curling skills.
Toro Rosso may have put only one 'candle' on Daniil Kvyat's birthday cake, but you can see why he was reluctant to try blowing it out!
With an incredible 13 years between them, like Kvyat, Williams' elder statesman Felipe Massa also celebrated his birthday last week.
Numerous teams are drivers were carrying this hashtag over the Russian weekend, sending their thoughts and best wishes to Billy Monger, the 17-year-old British F4 driver who lost his legs following a huge crash at the UK's Donington circuit a fortnight ago.

It's how Sebastian Vettel described him in Sochi last year after their infamous early collision. Twelve months on Daniil Kvyat could obviously see the funny side.
Ever wondered what it would be like to see you own face transformed into a Russian doll? The F1 drivers found out in Sochi - and Fernando Alonso seemed happy with his.
Keeping the balls in the air
In an F1 cockpit you need to constantly juggle a huge array of mental and physical task - perhaps no surprise then that three balls is an easy ask for Red Bull's Max Verstappen.
From showbusiness to the business of government, everyone wanted a slice of home driver Daniil Kvyat over the Sochi weekend.
Nice paint job!
It's amazing what goes on behind the scenes to make sure every Grand Prix weekend is a success. Here's a prime example from Sochi.
When in Rome...
...or Russia, it would be rude not to sample the local cuisine. Thankfully Pirelli's catering department were on hand to help.
Toro Rosso's camera crew took an unconventional route through the Sochi paddock.
From one Finn to another
Former F1 winner Heikki Kovalainen was among those delighted to see countryman Valtteri Bottas adding another chapter to Finland's illustrious F1 history.
