    The latest lids

    The evocative colours of the Brazilian flag and memories of the late, great Ayrton Senna helped inspire some memorable helmet designs.

    Love the hard work that the @BellRacingEU team put in to every one of my racing helmets. Thank you for making my custom design come to life this weekend! ⭐⭐⭐⭐ 🇧🇷 #LH4 #BrazilGP #BellHelmets #F1 @MercedesAMGF1 pic.twitter.com/SrKPh7QPq8

    The birthday boys

    We're used to seeing the odd cake or two over a race weekend, but Brazil seemed to have more than its fair share of celebratory bakes!

    Famous faces

    Renault were among the favourites for the 'most celebrity guests' prize at Interlagos, with superstar Brazilian singer Anitta among them...

    Remember your roots

    Both Mercedes drivers took the time to give a shout out to their parents over the Brazilian weekend...

    Happy Birthday, Mum. I love you ❤️ pic.twitter.com/9lQwa7vNLg

    Best of friends

    McLaren team photo shoot + Fernando Alonso + smartphone filming = one of the weekend's most endearing images.

    Farewell Felipe

    This time it was for real - and this time he went out fighting, after winning an epic scrap with old adversary Alonso.
