Justin Bieber, Khloe Kardashian in Calabasas' celebrity revolving door

Justin Bieber, the beleaguered pop star, sold his house in a gated community in Calabasas for $7.2 million to reality TV personality Khloe Kardashian.

The location puts Kardashian in proximity to sister Kourtney Kardashian should either need to borrow a cup of sugar. Kourtney bought the nearby home of retired pro football player Keyshawn Johnson this spring.

Khloe Kardashian's new house, built in 2005 and set on a 1.3 acres, was not listed for sale. Tax records show it has at least six bedrooms and 9,214 square feet of living space. That's a move up from the 8,000-square-foot Tarzana digs she previously shared with former Laker Lamar Odom.

Earlier marketing materials for the house, which was once home to actor Eddie Murphy's ex, Nicole Murphy, describe it as Spanish in style with hand-painted tiles, a courtyard, a 200-bottle wine cellar, six fireplaces, an elevator and two three-car garages. There's a swimming pool with a spa, a barbecue and a one-bedroom, one-bathroom casita with a kitchen.

Bieber, 20, bought the property two years ago for $6.5 million.

After run-ins with the police this year in Miami and Calabasas, the pop star once again drew negative publicity this month when videos surfaced of him using racist slurs. He has issued an apology.

The teen idol has released an album annually for the last four years. Among his hits are "Boyfriend," "Beauty and a Beat" and "As Long as You Love Me."

Bought home with a bigger bang

Kaley Cuoco-Sweeting and her husband, Ryan Sweeting, have sold their home in Sherman Oaks for $2.565 million.

The Tuscan-inspired house was built a decade ago. Designed for indoor-outdoor living and entertaining, it features an outdoor living room and fireplace, an outdoor kitchen with an eat-at bar, a swimming pool and a spa.

The 5,233 square feet of living space includes a family room, five bedrooms and five bathrooms. Stone fireplaces and interior arches are among architectural details.

The dressing room has extensive shoe racks, a shampoo/hair station with a salon bowl and two balconies.

Cuoco-Sweeting, 28, stars in "The Big Bang Theory." She also starred in the 2014 comic film "Authors Anonymous" and will be in "The Wedding Ringer" next year.

Sweeting, 26, is a professional tennis player. The two were married in December.

They sold because they bought the Tarzana home of former Laker Lamar Odom and television personality Khloe Kardashian this year for $5.499 million.

Stephanie Vitacco of Keller Williams was the listing agent for Sherman Oaks home. Mia Trudeau of Hilton & Hyland/Christie's International Real Estate represented the buyer.

A hangover from bachelor days

Justin Bartha of "The Hangover" films listed his bachelor pad for sale in Hollywood Hills West at $1.375 million, and in just over three weeks it was in escrow.

The vintage Spanish-style house of 1,416 square feet sits behind walls and gates with video surveillance. Vaulted beamed ceilings, separate dining and living rooms, a family room, a breakfast bar, two bedrooms and two bathrooms are among the features.

The 7,500-square-foot lot has a swimming pool, a hot tub and a covered patio.
