Forget the bangs made by fireworks on July Fourth.
Christina El Moussa rang in the summer holiday this week by showing off her banging bikini body ... while chilling with her shady new boyfriend a luxury boat in Newport, California.
Celebrity gossip outlets such as Entertainment Tonight have shared the sexy photos of El Moussa, who has said very little about her romance with Doug Spedding.
But a few sordid details have leaked out of late about the businessman.
For one thing, he actually dated Christina many years ago, long before she met, fell for and married Tarek El Moussa.
For another thing, the car dealer has been sued on a number of occasions for alleged bad business practices.
According to Orange County court documents, Spedding has not always been so customer friendly, having been accused in 2008, for example, of deceiving customers into purchasing a more expensive vehicle than they had intended to buy.
For a third thing, he may be equally untrustworthy in his personal life.
Some woman named Tracy Johnson-Diaz has come forward and shared text messages that she claims prove she’s been sleeping with Spedding throughout his relationship with El Moussa.
In one text obtained by Radar Online, Spedding comes directly out and asked Tracy if she wants to "f-ck right now."
To be fair, as you can see above, there's no way to validate whether these texts were sent by Tracy or Doug or on what date or really anything at all.
This isn't exactly evidence that would hold up in a court of law.
In the court of public opinion, however, Christina isn't known for having the best taste in men.
She and Tarek came across like a regular, very happy couple during the early years of Flip or Flop on HGTV.
But they separated in the spring of 2016 and Tarek filed for divorce earlier this year.
Both reality stars have been busy ever since trying to win the PR game, sharing photos of their new and improved bodies on social media, while also gushing over their two little kids.
Christina, meanwhile, dated the family contractor (Gary Anderson) last year, prior to moving on here to Spedding.
In June, an insider told Entertainment Tonight that the relationship was "new," but exciting and full of potential to be serious.
"Christina and him recently reconnected," the source said at the time, explaining that the two have known one another for over a decade and adding:
"She dated him before her and Tarek were together."
As a result, previous reports claimed Tarek was very jealous of the courtship, but he swears this isn't the case.
“She’ll call me and ask how’s my cancer remission, how are the doctors," Tarek told E! of Christina recently, insisting that he and his ex-wife are on solid terms.
"I’ll call and ask the same about her, how she’s doing, how she’s feeling. We still deep down care about each other."
This is a good thing because they're sort of stuck with each other for awhile.
HGTV has ordered more episodes of Flip or Flop, meaning Tarek and Christina will continue filming for another few months, side by side.
Even more urgently, they are parents to a six-year old daughter and a one-year old son.
Both have emphasized again and again how these kids will always be their priority.
So even if Tarek is fuming that another dude gets to touch the body underneath Christina's bikini, he'll have to remain as chill about it as possible.
It's all about the well-being of his children from here on out.
