New Zealander Cullen spent seven years alongside Hamilton before parting ways last month but seemingly still keeps in touch the exploits of the seven-time World Champion and Formula 1.
Ahead of qualifying for the Australian Grand Prix last weekend, Cullen took to her Instagram to give fans an insight as to what to look out for in order to tell Hamilton was mentally prepared for the session ahead.
She revealed that the sign came in Hamilton’s hands and said if they were “dancing” when he was in the garage, then that is a sign “he is in the zone.”
“It’s Qual. My favourite time of an entire race weekend,” she posted. “Looking for that perfect single lap, car set up meets precision driving,
“The perfect quali is where you build each lap, learn from the previous, implement and profit in the following. [I] just love the focus and attention.
“Watch for Lewis’ hands when he is sitting in the car in the garage, if they are dancing you know he is in the zone. Let’s go .. “You can have a perfect quali as a driver regardless of end position, that is the goal.”
Hamilton would go on to achieve P3 in the session in Melbourne, his best qualifying position of the season so far, before improving on that to P2 in Sunday’s race.
The split between Cullen and Hamilton came as a surprise but the Mercedes man revealed it was entirely amicable, suggesting that the demands of Formula 1 eventually take their toll.
“It’s an incredibly challenging role I think for anyone in those positions,” Hamilton told Sky F1 ahead of the Australian Grand Prix weekend.
“It is a lot of travelling and a lot of time away from your family and you grow incredibly close together.“
If you’re at dinner, during your weekends and while you’re travelling, it’s usually you, your trainer or physio, your family or whatever it may be, it’s incredibly intimate in that sense. And you become great friends.
“Angela is living her life right now. She’s got so many great ideas of things she wants to do.
“We talk and message pretty much every day. We’re still going to go skydiving together and we’re always going to be in each other’s lives. We’re stuck with each other, unfortunately or fortunately!
“We’ve been through thick and thin so I’m grateful our relationship is as good as it is and I think we’ve probably had one of the longest relationships in the sport, so incredibly grateful for her and I love her dearly.”
