Cullen has shared insights into their sporting journey via social media, and her latest life update includes motivational advice for followers.
What is Angela Cullen doing now?
After departing from her role alongside Hamilton and Mercedes, Cullen took a professional break, but she is now back in motorsport.
For the 2024 season, she began working with fellow New Zealander Armstrong, who drives the No 11 car for Chip Ganassi Racing in IndyCar. The two appear to have formed a good friendship, and 23-year-old Armstrong has spoken of the benefits of having Cullen in his team.
Away from the track, Cullen is fond of sharing motivational posts on her Instagram, and recently delivered a new message.
"The journey you are on is not random, it’s meant and designed for you," she wrote on the platform, alongside a selfie in front of a colourful mural reading 'Love'.
"Every detail in your life connects with everything else and there is always a purpose for everything," Cullen continued.
"Don’t get discouraged, but pay more attention to patterns and signs. You have everything you need."
