Noah Cyrus allegedly was "offended" when her mother, Tish Cyrus, pursued and married Dominic Purcell despite knowing her daughter had a relationship with the "Prison Break" star, a new report claims.

An unnamed insider told People that Noah, 24, and Purcell, 54, "were seeing each other in a friends with benefits way, off and on" before he got together with her mother, 56.

While Us Weekly reported last week that Noah allegedly thinks Tish stole Purcell from her, People's source said there was no overlap between the two relationships.

"[Noah and Dominic] stopped seeing each other and then Tish started something up," the insider added.

However, this allegedly did not stop Miley Cyrus' younger sister from being quite "offended" by her mom marrying her ex-lover, according to the source.

The insider claimed that Tish knew Purcell and her daughter dated but "never gave Noah the chance to talk about all of this before they got married."

Noah, Tish, and Purcell have not publicly addressed the reports.

But the claims were backed by a report from Entertainment Tonight, which cited an unnamed insider as claiming that Tish "did not tell" Noah when she "decided to pursue" Purcell.

Tish tied the knot with Purcell in an intimate ceremony in Malibu, California, in August 2023 -- more than a year after she and ex-husband Billy Ray Cyrus filed for divorce following over 28 years of marriage.

Billy Ray, who shares five children with Tish, married Australian musician Firerose two months later.

Rumors of mother-daughter drama first surfaced last year after Noah and her brother Braison skipped Tish and Purcell's wedding, where Miley served as maid of honor.

Noah and Braison instead spent time together perusing the aisles of a Walmart, as seen in their Instagram Stories at the time.

While ET reported at the time that there was "no family drama" surrounding the wedding, the insider claimed to the outlet this week that Tish allegedly did not want her two children at her big day.

ET's source claimed that Tish chose not to invite Noah and Braison to her wedding and "blocked them on Instagram after she pursued Dominic."

"It was Tish who requested security at her wedding to keep Noah and Braison out," the insider added.

The source claimed that Miley had "no idea" that her younger sister previously dated their mom's husband.

Miley Cyrus returns to Malibu for a video shoot, which many believe (and fans hope) is for her music video.

Meanwhile, Noah appeared unfazed by the reports of alleged drama with her mom as she appeared at Paris Fashion Week Friday.

The singer sat front row at the Vetements Womenswear Fall/Winter 2024-25 show with her fiancé, fashion designer Pinkus.

Photos published by Page Six showed Noah rocking a see-through black lace dress and bleached eyebrows.

Pinkus, for his part, donned a light gray button-down and matching, baggy trousers for the outing.

The couple announced their engagement in June last year.

Noah wrote on Instagram at the time, "The greatest moment of my entire life was saying 'yes' to spending the rest of ours together."

She added, "This past month of being your fiancé and being in our own little world of just us two has been so perfect and I wish i could never leave this time."

Noah also described her beau as "the most talented, the most loyal, [and] the kindest person."
