Singer Avril Lavigne is engaged to her boyfriend of nearly two years, Sum 41 frontman Deryck Whibley, according to US Weekly. The magazine reported that Whibley, 25, proposed to Lavigne, 20, over the weekend while Lavigne was finishing up the European leg of her tour. The two hail from Ontario and reportedly bought a home together in Los Angeles last year . . . Moscow has been added to the lineup of international Live 8 concerts on Saturday. The full artist roster for the Red Square gig wasn't posted on the organization's Web site, but the show will reportedly be headlined by Pet Shop Boys and feature several Russian acts . . . U2 went to court in Dublin yesterday in an attempt to recover more than $6,000 worth of memorabilia from former stylist Lola Cashman, who claims the items (including a pair of lead singer Bono's pants) were gifts from the band. Cashman, who published an unauthorized biography of the group last year titled "Inside the Zoo with U2: My Life With the World's Biggest Rock Band," had tried (unsuccessfully) to sell the items at auction . . . On Aug. 30, Starbucks stores will exclusively sell a CD of live Bob Dylan recordings from New York's Gaslight Cafe in 1962.
