The images flipped from one to the other as James Taylor’s song Mexico plays. ‘Ohhhh Mexico it sounds so sweet with the sun sinking low, the moon so bright with the night alight…. making everything all right,’ croons Taylor. 

Joanna was seen in a black bikini as she fell backwards into a swimming pool at a modern gray mansion as Chip napped on a lounge chair.

The two were also seen dressed up for a dinner date; she had on a blouse with jeans and he in a blue shirt.

And the pair were also seen having lunch at a restaurant as they enjoyed a salad and tacos.

The two pulled the plug on their hugely popular HGTV reality show Fixer Upper in 2017 after five seasons.

But they quickly found a new and bigger opportunity when they made a deal with Discovery Plus in 2018 to launch their own Magnolia brand channel.

Earlier this year the duo shared that fame and success has not been all easy.          

Chip revealed to Oprah Winfrey in March that he ‘lost a part of myself’ on account of the fame he achieved through Fixer Upper.

The 46-year-old TV star shared that his wife handled stardom better as it was ‘no big deal’ to her.

In a preview clip obtained by People he revealed that he and Joanna tried ‘to unpack’ his issues after Fixer Upper ended in 2018 and they took a year off. 

Oprah raised the subject by pointing out that ‘if you don’t know who you are when the fame thing hits then you lose yourself.’

She asked her guests: ‘Did you all start to sense that or did you know that you were grounded before the fame thing hit?’

The talk show icon elaborated: ‘You were so grounded, had your own life, the four kids and you took the time off because you wanted to reground?’

Chip replied that ‘I wanna speak on Jo’s behalf because she would never say things like this, but she is so incredibly wise, so incredibly grounded.’

The star said sweetly: ‘All the things that you just described is who Joanna is, and to be really frank I thought that’s who I was also.’

He confessed: that ‘the truth for Jo and I was it was no big deal for her, but for me to become famous I lost a part of myself that was really, it was sad.’

Chip continued: ‘And I would say it took me a year or two while I was still filming to try and grapple with what exactly it was that I was losing.’

He noted that ‘then that year off I really think that Jo and I were able to kind of hunker down and really kind of try to unpack what it was about fame that seemed so incompatible with my personality.’
