Miranda Lambert collaborated with Anderson East on new album

NASHVILLE, Oct. 18 (UPI) -- Miranda Lambert revealed Monday that she and boyfriend Anderson East collaborated on her new album.

The 32-year-old country star co-wrote two songs, "Getaway Driver" and "Well-Rested," with the 28-year-old singer for her record The Weight of These Wings, which is scheduled for release Nov. 18.

The Weight of These Wings is a double album divided into the discs The Nerve and The Heart. Lambert, who co-wrote 20 of the record's 24 tracks, also collaborated with such songwriters as Natalie Hemby, Ashley Monroe and Nicolle Galyon.

Lambert and East confirmed their relationship in December following the country's star's divorce from Blake Shelton in July 2015. Sources told E! News this week that the couple are considering marriage.

"She wants to get married again and have children soon," an insider said. "That has been an open conversation between her and Anderson. He wants the same."

"Miranda is very happy with Anderson. They have gotten very close," the source added. "She is completely over Blake and wishes him only the best. It was a time in her life that was special, but she's happy that relationship took her to where she is now."

Lambert last released the album Platinum in 2014, and released a first single, "Vice," from The Weight of These Wings in July. The star will promote the new record on her Highway Vagabond tour in 2017.

"Miranda is at the top of her game now. She loves how she feels from the inside out. Her close friends and family feel like she is back and better than ever with how her personal life is going and also her career," an insider told E!.

"She can't wait to tour and have the country hear her sing again. This new music is very special to her and you will hear some songs that reflect her life and situations she has been through over this year. People will relate," the source added.
