He paid tribute to the patriarch of the family.

Ant Anstead honored his late grandfather with a touching memorial shared to Instagram on Tuesday morning.

The 42-year-old reality star posted a snap of 'four generations' of Anstead men before writing a few kind words to honor his gramps.

'Four generations captured in one picture,' he wrote in the caption of a snap with his father and son Archie. 'Now three generations. Rest In Peace Gramps! 

'What amazing memories like skinny dipping on Bodmin Moor, Pogle camping adventures and those denim hot pants! Go be with Nanna you pair of hippies!'

The Master Mechanic host shares 14-year-old son Archie and daughter Amelie, 18, with ex-wife Louise.

He recently went public with his relationship to Renee Zellweger after the couple met earlier this year while working on his Discovery+ show, Celebrity IOU Joyride.

Speaking to PEOPLE (The TV show!) last month, Ant said: 'I'm really grateful to the show because these amazing things happen in your world and sometimes when things collide, they collide at the most obscure times when you least expect them.'

He added: 'And that's what happened in this case. I'm grateful for that.'

In a separate September interview with the outlet, Ant confirmed that his and Renee's relationship is 'something that's really private.'

Earlier this year, Ant finalized his divorce from fellow reality star Christina Haack.

The pair married in a surprise wedding at their home in California and had a son, Hudson, now two, but by September 2020 it was all over.

Haack has since found love in the arms of former cop and new fiance, Joshua Hall, and continues to co-parent her two children with ex-husband Tarek El Moussa, who recently became a married man once again when he said 'I do' to Selling Sunset star Heather Rae Young.
