If reports are to be believed, Mariah Carey and Nick Cannon may be moving on up to a mansion in Beverly Hills. The couple has reportedly made an offer on the world’s most expensive house currently on the market.

Fleur de Lys, the five-acre estate in Holmby Hills, is listed at $125 million. The palatial 15-bedroom mansion was built by Texan billionaire David Saperstein. According to Luxist, the 41,000-square-foot French limestone mansion features Italian marble walls, French limestone floors, gold-embossed leather wall coverings, gold-leaf crown moldings, a ballroom with ceiling frescoes, a library complete with rare books, two kitchens, and a screening room with seating for 50.

There were earlier reports that Mariah and Nick were looking to make permanent residence on the West Coast while Mariah records her new album and pursues acting. “They like the home because there’s so little that needs doing to it,” a source tells Contactmusic.

We can’t wait to see that episode of “Cribs.”
