Spice Girls star Geri shared a trio of touching pictures of the father-son-duo as Red Bull Racing Team Principal Christian gave his four-year-old boy a guided tour of his day job.
Geri, 48, was on hand to catching the moment as Christian, 47, tenderly held Monty in his arms as the youngster looked enthralled with all of the Red Bull racing cars.
“My boys,” penned Geri, with two heart emojis for good measure.
“Good luck! @christianhorner @redbullracing #AustrianGP.”
Monty was treated to a close and personal view of the track and Red Bull garage ahead of the start of the Austrian Grand Prix, which starts on Sunday.
The little boy was dressed in a matching navy Red Bull racing shirt like his dad as he enjoyed a day in the fast lane.
Another snap showed the pair watching the cars speed around the track and checking out the high-tech equipment.
“He is a mini you Geri!” gushed one excited fan.
“Ginger Boys, I love you Geri, kisses from Mexico,” commented another.
A third reacted: “Omg. Love this so much!! Hope mine who’s coming it a little gingee!!”
“Mini Geri,” said another of Geri’s 1.1 million Instagram fans.
“Your son is absolutely adorable and has your fantastic red hair,” followed by a red heart emoji.
Another joked: “Learning his trade early lol.”
Geri’s sweet photos come soon after it was revealed fellow Spice Girl Emma Bunton secretly married her partner of 23 years, Jade Jones, but none of the group were invited to the intimate ceremony.
The girls are all on good terms and Geri toasted their “special bond” by also sharing a sweet throwback snap of the group to celebrate 25 years of their smash debut single Wannabe.
“25 years of ‘Wannabe’,” reflected Geri. “Wow. The song that changed the lives of five girls from Britain.
“The first picture was taken in my back garden on a Sunday – we were all listening to the radio together that day we went to number 3 in the charts!!
“The black and white picture was from our first ever photoshoot!
“And the famous ring… I bought a gold ring for each of the girls when we first got together, as a symbol of our friendship.
“It’s a special bond that continues to stand the test of time. I’m so proud of everything we have achieved together, girls.
“BIG thank you to our amazing fans from all over the world for your support and loyalty. “Love, Ginger. @emmaleebunton @melanimusic @officialmelb @victoriabeckham.”
