One of our faves, Britney Spears, seems happier than ever with new boyfriend Charlie Ebersol, but not everyone in his camp is convinced she's the right one for him!

Charlie's mom, actress Susan Saint James, "cannot believe that her son is getting serious with Britney," a source tells Radar Online.

And she isn't basing her opinion on hearsay. Both Susan and Charlie's father, NBC executive Dick Ebersol, have reportedly met the "Toxic" singer.

“Charlie introduced Britney to the both of them as his girlfriend, but they do not agree about her,” the insider reveals. “Dick thinks it is great to see his son happy, but Susan wants him to be with someone not famous.”

You can't get more famous than Brit, who has hit more than a few bumps along the way — remember the shaved head fiasco of 2007?!

“All Charlie’s mother has ever wanted is for him to get married and have children,” the source tells the site. “She just doesn’t think Britney is the right choice.”

For the Grammy winner, who just turned 33 on Dec. 2, she can't get enough of the 31-year-old producer, who keeps popping up on her Instagram page.

The biggest sign that the pair are getting serious? The blonde beauty posted a picture of her, Charlie and her two sons — Sean, 9, and Jayden, 8 — on a beach, captioning the cute snapshot, “So grateful for time this weekend. ❤ my boys!"

Let’s hope Susan comes around because Brit Brit could very well become her daughter-in-law in the near future!
