Singer 'Let Go' and got a bundle

The peerless, fearless Avril Lavigne has done what others only dream of: No, not the part about snagging eight Grammy nominations on your first album when you are still in your teens. Rather, it's the part where you list your Beverly Hills-area mansion and somebody gives you a cash offer of $5.2 million just 36 days later. Tears of joy may have even run down her 23-year-old face, trademark thick black eyeliner and all; they certainly would have mine.

Lavigne's five-bedroom, six-bathroom house has 6,864 square feet. It is "nestled serenely," says the listing, on a private lot in exclusive Mulholland Estates. There are tropical gardens with a pool, spa and a north-south tennis court. The kitchen is described as gourmet and opens to the family room on one side and an attached butler's pantry and formal dining room on the other. There is a library.

The house was listed at $5.8 million, but when cash comes calling, it behooves one to listen.

Speaking of listening, many people apparently do: Lavigne's debut album, "Let Go," went platinum six times and included the song "Complicated," which earned the singer five Grammy nominations.

In July 2006, she married Deryck Whibley, guitarist and lead vocalist with pop punk band Sum 41.

Mauricio Umansky of Hilton & Hyland, Beverly Hills, was the listing agent, and Alan Parness of Rodeo Realty Inc. in Studio City represented the buyer, according to the Multiple Listing Service, Combined Los Angeles-Westside (CLAW).

For sitcom alum, a lot of taxi fare

"Who's the Boss?" star Tony Danza may have learned it wasn't he in this real estate market. Not to worry, big guy, it's just the market.

Danza, 57, initially listed his 6,778-square-foot Sherman Oaks house at $6.15 million. It was subsequently dropped to $5.65 million. The MLS shows a sale price of $5 million.

The house has five bedrooms, 5 1/2 bathrooms and sits on 2.3 acres in the exclusive Longridge Estates area. Cape Cod in style, the home underwent a substantial remodel in 1997. The gated property includes a guesthouse, tennis court, batting cage and pool-spa.

Danza was part of the ensemble cast of TV's "Taxi" from 1978 to 1983 and then starred in the sitcom "Who's the Boss?" from 1984 to 1992. He owns a 1,392-square-foot beachfront home in Malibu, according to public records.
