Elvis is so cool, why would he marry her? And don’t tell me “For love”!

Diana Krall, Elvis Costello to marry
Canadian jazz phenom Diana Krall and singer-songwriter Elvis Costello are engaged to be married, Krall’s father has told the Victoria Times Colonist.
Jim Krall, a Nanaimo, B.C., accountant, said Thursday he doesn’t know any details about when or where the wedding might take place but said he’s happy about the plan, the newspaper reports.
Rumours of a romance between Krall, 38, and Costello, 48, spread after the duo was spotted dining together at a New York restaurant in January.
“It’s a wonderful thing and it’s special to me. I’m really happy,” she said of the relationship earlier this year.
Costello came on the scene as a rocker in the late 70s with the album My Aim is True. Krall has had a series of popular albums and won a Grammy this year for best jazz vocal album for Live in Paris.
The Times Colonist said a source at Sam Feldman & Associates, the Vancouver company that manages Krall, confirmed the engagement but declined to provide details.
Back in November, Costello split from his wife, ex-Pogues singer Cait O’Riordan, after 16 years of marriage.
