Britney Spears' ex Sam Asghari looked to be having fun in Texas as her bombshell tell all book The Woman In Me drops.

The 29-year-old actor was seen at a US Grand Prix party in Austin this weekend.

The handsome workout fanatic was wearing a cowboy hat and boots with jeans at the Sports Illustrated Circuit Series, the official After Party of COTA. 

Also there were Mark Consuelos, Cole Hauser and Becca Tobin among other race fans, and featured Wagoneer by Jeep.

It has been quite the week for his ex Britney whose new book has dished on Justin Timberlake, Madonna and Colin Farrell.

But she had nothing but nice things to say about Asghari in her newly-released memoir, The Woman in Me, which hit shelves Tuesday. 

Despite the recent end to their 14-month marriage, after he filed for divorce due to 'irreconcilable differences' in July, the pop star, 41, described her former partner, 29, as 'a gift from God.'

'I have an appreciation for how stable he is. I love that he doesn't even drink,' she wrote of Asghari, who she met in October 2016 while shooting the music video for her hit track, Slumber Party.'

The mom-of-two told also told readers that she 'knew' she wanted him in her 'life  immediately.'

'The chemistry with us in the beginning was insane. We couldn't keep our hands off each other,' she recalled. 

 The Grammy winner also credited her former lover for giving her the strength to speak out against her 'abusive' 13-year conservatorship.

During her open court hearing in June 2021, Spears said Asghari 'squeezed' her hand as a signal of his support. 

'I look up to him — his consistency with working out and being a good man and being healthy and taking care of me and helping me learn how we can take care of each other,' she gushed. 'He's such an inspiration and I'm grateful.'

Sources told Page Six that Spears had already turned in her final manuscript for her book ahead of their split. 

When asked if he was nervous about the tell-all coming out, Asghari told TMZ he wasn't and had 'already read it.'

'I'm very proud of her and, you know, she put a lot of work to it, and it was very hard so I'm definitely excited and I'm extremely proud of her,' Sam continued.

On the songstress penning the book, he stated that, 'It was a tough one.' In conclusion, he added, 'I'll be the first one in line to buy it.'

Her father, Jamie, however, reportedly has an opposite viewpoint about the memoir. 

A source told TMZ that he has no intention to read the book, adding he's, 'not sweating what Britney has to say about him in her new book...'

The insider continued, 'she's already trashed him both in court and on social media, once saying she hoped he'd spend the rest of his life in jail. '

Back in August, Sam notably filed for divorce from Spears after a little over one year of marriage. He cited 'irreconcilable differences' as the reason for the split and is asking for spousal support from the performer, as well as coverage for his legal fees.

Due to an 'iron-clad prenup,' Sam will not profit on her upcoming memoir. He is mentioned in the book, but 'not a lot,' a source recently told DailyMail.com. 

However, sources told TMZ that the singer made 'some changes' to the memoir following their separation.

 When she spoke out about the divorce for the first time since the divorce news came to light, Britney admitted that she was 'a little shocked' but 'couldn't take the pain anymore...'

The star later expressed that she would focus on staying 'strong' and concluded with, 'And I'm actually doing pretty d**n good!!! Anyways have a good day and don't forget to smile!!!'

Asghari has previously claimed that Britney had gotten 'physical' with him on various occasions during the course of their relationship.
