ROSIE O'DONNELL will soon be raising her own “Modern Family” version of the “Brady Bunch!”

The former TV host is set to welcome her sixth child with her new squeeze – singer and songwriter Sophie B. Hawkins, The National ENQUIRER can exclusively reveal.

“Rosie’s been attending Sophie’s concerts at least since the fall,” according to a source.

Grammy-nominated Sophie, who announced her pregnancy in February, looked at least four months along at an April 30 gig at New York City’s Rockwood Music Hall Stage 3, according to an eyewitness.

Rosie – embroiled in a bitter divorce and custody battle with Michelle Rounds – didn’t look “worse for wear at Sophie’s show,” said our on-site spy.

“She looked like she was having a good ol’ time!”

The comedian caught Sophie’s show with four female friends, and seemed to take a veiled dig at her soon-to-be ex-wife, said the onlooker.

“Right after Sophie sang, ‘I can’t replace you. I’m better off without you,’ Rosie boisterously yelled out from her perch at a stage-left table, ‘I agree!’”

Afterward, the loved-up pair left together in a black SUV – but not before an ENQUIRER photographer caught these snaps, far right.

As we previously reported, 53-year-old Rosie left her co-hosting gig on “The View” on Feb. 12, and filed for divorce from Michelle on Feb. 27, although the couple actually split late last year.

In early March, Rosie and Sophie, 50, “were all over each other” at the Broadway play “On the Twentieth Century,” divulged another insider.

Now their public chumminess seems to validate rumors that Rosie was seeing the singer while still married to Michelle, leading to the collapse of their two-year union!

Rosie kept the romance on the down-low to avoid complicating her divorce proceedings, sources said.

Meanwhile, Michelle, 44, has been snapped stepping out with model and TV personality Carmen Ortega.

In a magazine interview, Sophie – whose hit “Damn I Wish I Was Your Lover” was a 1992 chart-topper – revealed she’d used one of 15 embryos she froze at 31.

The singer has a 6-year-old son, Dashiell.

Rosie already has three daughters and two sons, making her just one boy short of a modern “Brady Bunch.”

She’s divorced from first wife Kelli Carpenter.

A source exclusively told The ENQUIRER: “Sophie has told friends ‘on the QT’ she is with Rosie, and those close friends say they are having the kid together.”
