They found their happily ever after — without a prince.
New besties Brooks Nader and Madelyn Cline have put their mutual ex, Prince Constantine Alexios of Greece and Denmark, behind them, a source exclusively tells Page Six.
The “Love Thy Nader” star and “Outer Banks” actress were spotted having a “girls’ night out” at the Chateau Marmont in Los Angeles, Calif., Sunday night.

“Neither of them cares that they share a mutual ex,” our insider says, referring to their former relationships with the 27-year-old Glücksburg dynasty descendant.
The source continued, “They’ve become good friends and enjoyed a fun girls’ night out with drinks at the Chateau.”
We hear Nader’s friendship with Cline is “recent,” but that they have hung out a few times before.

The model, 28, was dressed stylishly for the outing in jeans and a black plunging halter top layered under a fur shrug. She also wore black Louboutin heels.
The “Glass Onion” star, also 28, looked chic in a black blazer dress, sheer black tights and pumps.
Nader debuted her relationship with the eldest son of Crown Prince Pavlos and Crown Princess Marie-Chantal of Greece in 2024.

She and Alexios took their love public when they attended Olivia Culpo and Christian McCaffrey’s wedding in Rhode Island in July of that year.
Just two months prior, Page Six revealed that Nader and Billy Haire were divorcing after four years of marriage. (They finalized their divorce in May 2025).
Things between Nader and Alexios fizzled, and she started dating her “Dancing With The Stars” partner, Gleb Savchenko, in a whirlwind romance that ended in April 2025 after eight months together.

Meanwhile, Cline had a brief fling with the royal last year.
In September 2025, Cline and Alexios were seen locking lips at a bar in New York City. Days later, they were spotted showing PDA during a night out on the town.
It’s unclear if Alexios — who previously dated Poppy Delevigne and is Prince William’s godson — is single at the moment.
Both Nader and Cline appear to be unattached — with the Sports Illustrated Swim star shutting down rumors this week that she is dating Ben Affleck.
