Variety has exclusively learned that Chip and Joanna Gaines' Magnolia Network lineup, including all five seasons of HGTV's "Fixer Upper," will be available on HBO Max in September.

"Select" Magnolia Network titles will be available on the streamer on Friday, Sept. 30, including "Fixer Upper: Welcome Home," "Magnolia Table with Joanna Gaines," and "The Lost Kitchen."

In partnership with Discovery, the former HGTV stars launched Magnolia last year, before Discovery merged with WarnerMedia.

The new series "Fixer Upper: The Castle," about the Gaines' renovation of their 100-year-old castle in Waco, Texas, will premiere on HBO Max on Oct. 14 along with Magnolia Network and Discovery+.

WBD sources say Magnolia Network content will eventually be added to HBO Max, but will also remain available on Discovery+, which costs $4.99 per month with commercials compared to HBO Max's $9.99.

A Warner Bros. CEO David Zaslav and co. are expected to reveal more about HBO Max, Discovery+, and the rest of Discovery's plans later today during Discovery's Q2 earnings report and presentation.

A linear channel rebranded from Discovery's DIY Network launched in January. Magnolia Network was first launched as an app inside Discovery+ last July.

In April, Variety exclusively reported that Discovery would acquire WarnerMedia and rebrand as Warner Bros HBO will now oversee the Magnolia Network, a joint venture between Discovery and the Gaineses

With this new structure, Magnolia president Allison Page now reports directly to HBO and HBO Max content chief Casey Bloys.

A few top WarnerMedia executives remain after the mass exodus began ahead of the Discovery-WarnerMedia merger's close and has continued as Zaslav slowly unveils his new leadership team.

HBO and Bloys are heading up the lifestyle brand from the "Fixer Upper" stars, rather than Warner Bros.

With the Gaineses' origins as HGTV icons, Kathleen Finch, Discovery's chairman and chief content officer, is a notable sign of integration between the two companies.
