The pin has been pulled, but the grenade has yet to go off. A $53-million deal is in the works for a storied estate in Beverly Hills — a price that would make it the most expensive sale in all of Los Angeles County this year.

Hotelier Brad Korzen and noted designer Kelly Wearstler have entered into an agreement to sell their longtime estate, which was once owned by movie producer Albert Broccoli, to designer and filmmaker Tom Ford.

The 3.2-acre estate includes a seven-bedroom main house, a guesthouse, a swimming pool and a tennis court. A gym and a screening room are among the features.
