Justin Herbert and Jaxson Dart might as well break up with their girlfriends now … because a famed astrologist says their relationships aren’t written in the stars.

Richard James — host of the “StarCast Weekly” show — starts out by breaking down the Los Angeles Chargers star QB’s relationship with his pop star better half, Madison Beer … which Richard says is unlikely to work out because they’re both Pisces.

Plus, James isn’t sure the two are sexually compatible … arguing that because Herbo’s Mars is in Aries, he’s more sexually spontaneous … while Madison might be a bit freakier but ultimately looking for something more long-term.

As for Dart — who is dating model Marissa Ayers — James says the Giants’ QB is attracted to her confidence … but communication is key here, and the stars dictate they have a giant issue there.

Both the Chargers and Giants are out of the playoffs … so, they’ll have to wait until next year to win it all … and wait until their next relationship to find happily ever after, if James is right.

Sure, it might be cold out there, but we’re feeling the heat right about now … because we’re sharing Quenlin Blackwell‘s hottest shots!

And it’s the right time to go through them, too, because it’s her big 2-5 on Saturday … and you’d best believe we’re celebrating her birthday!

Devin Haney is firing back after his ex-fiancée, Leena Sayed, filed legal papers in hopes of posting their kid on social media without his approval — claiming her OnlyFans career is a good reason to keep their one-year-old off her pages.

As we previously reported, Sayed wants to modify the couple’s custody order on their kid … so she can share pics of Khrome without Haney being involved. As it stands, both sides have to sign off on any kid pics on the internet.

According to court docs, obtained by TMZ Sports, Haney’s legal team said the stipulation “does not unduly restrict Leena’s self-expression,” after she claimed “social media is an important part of how I share my life with friends, family, and my social media followers.”

The filing adds … “The common sense point is that a celebrity’s child on social media invites trouble. And Leena presents herself not only as a celebrity, but as a wealthy and fantasy-inducing celebrity.”

Devin also addressed Leena’s point that she can only share posts about their child if she is in “some proximity to his presence” — including an exhibit in which he reposted a picture of Khrome watching him fight in Saudi Arabia.

“I learned that Leena wanted to post a picture showing the back of Khrome’s head in front of a television screen on which I appeared in the ring,” Haney wrote. “I approved. I was carried away by the fight’s result and by seeing Khrome watching me, and did not exercise appropriate caution.”
