Shania Twain Is Singing the Blues
"She's spending as much time with Eja as possible and hasn't put down her guitar since the split," a source close to singer tells PEOPLE. "The songs are pouring out of her."
No doubt some of them – like many great country songs – are inspired by heartache. Twain, 42, announced her separation from Lange, 59, in May, after she found out about his alleged affair with one of her best friends.
Twain is also keeping busy shopping and traveling. The now-single singer was recently spotted buying lingerie at a Holt Renfrew store in her native Canada. She's also been to the Caribbean, where she has a villa, and to Switzerland, where she and Lange once lived together.
Last weekend, Canadian fans were surprised to see their homegrown talent whiz through the Toronto airport wearing dark shades, but also sporting a big smile.
