Rey Mysterio is a WWE legend ... but he won't go down as the best wrestler in the family, 'cause the Grand Slam champ tells TMZ Sports his son, Dominik Mysterio, will actually be better than him!

We talked to the 46-year-old wrestler ahead of the 30th season of Raw, premiering Monday night, and we asked about his WWE Superstar son's ascent as one of the best wrestlers in the world.

"I've told my son from the beginning, you're gonna be better than your old man and I keep saying this over and over and over to him," Rey says.

"I can't wait for the day for him to become his own man, although in a way he already is and for me it's hard as a father to kind of let him go and fly on his own, but I truly believe in my heart, and I don't just say this so he can stamp it in his head, but he's gonna be better than his old man."

That's saying A LOT ... Rey has been the World Heavyweight Champ, 3 times, Cruiserweight Champ, 3 times, Intercontinental Champ, twice ... among a bunch of other championships.

Speaking of titles, Rey and Dominik actually won the tag team title together ... a first for a father and son.

We asked Mysterio where the moment ranked in his career of awesome accomplishments ... and it was clearly an unforgettable moment.

"Top three, without a doubt!"

And, get this ... Rey says his son's success has actually motivated him to continue kicking ass in the squared circle as he ages.

"It motivates me, it inspires me to keep doing what I'm doing because I'm seeing my son kickoff!"

Britney Spears is heading toward major life changes, but one thing that will remain constant is the custody arrangement for her 2 sons ... at least according to Kevin Federline's attorney.

Mark Vincent Kaplan tells TMZ ... even if Britney's conservatorship is dissolved next month, as she and others expect, the custody agreement she and K-Fed have for their boys -- Sean Preston and Jayden James -- will likely not be impacted, partly because of their ages.

Kaplan says teenagers -- the boys are 16 and 15 -- get a lot of say in court about what's best for them ... and, basically, the current arrangement ain't broke, so no one's looking to fix it.

As things are now, and have been for years, Britney and Kevin's agreement is she sees the boys based on when she wants to see them ... and also on what they want.

Kaplan tells there's us there's no need to switch things because everyone's happy, and at Sean and Jayden's ages there's less concern about their supervision at all times.

Kelly Clarkson has been a single woman for nearly 2 months, TMZ has learned, but a clerical error has thrown everyone off the scent.

Brandon Blackstock's lawyer, Samantha Spector, filed legal docs which lays out what has been decided so far in the divorce and what issues remain. There's a notation in the docs, saying the actual divorce will become final on 1-7-2022. That obviously makes it seem like Kelly and Brandon are still married.

We've learned this was a screw-up by the clerk, who mistakenly wrote 1-7-2022. In fact, Kelly and Brandon have been divorced since August 3. We're told the clerk is correcting the mistake.

TMZ broke the story ... the judge has already upheld the prenup -- something Brandon was aggressively contesting. There was a trial and the judge said Brandon signed it fair and square. That said, the property issues should be fairly easy to resolve, although in a nasty divorce -- which this is -- nothing should be taken for granted.

Kelly's income is separate, and considerable ... she earns $1.9 million a month. Brandon makes $10k a month.
