I called new album Paula because is is about her:

Singer Robin Thicke called his new album Paula because he did not want to trick fans into thinking his heartbreak tunes were about anyone other than his estranged wife.
The 'Blurred Lines' hitmaker said the record is not a veiled attempt to win back his actress wife, reported Contactmusic.
"I came right off a tour and I had all these songs and all these ideas and feelings in my heart. And I went right into the studio. I wrote all the songs in about three weeks and we recorded the album in about a month.
"Obviously all the songs were about her or about how I feel about her. A lot of songwriters have done this kind of thing before. They won't tell you in the title or they'll be suggestive I was just like, 'There's no reason to hide who this is about'. It's all about her," he said.
