The 24-year-old singer, who is known for her songs about lost love and heartbreak, is going to focus on her newfound happiness with Simon Konecki and the impending arrival of their first child, reported Contactmusic.
"It will be lighter than her last ode to break-up. The pregnancy has had a big impact on her songwriting," a source said.
Meanwhile, the couple are preparing for the baby and Adele is enjoying her time out of the spotlight.
"She is lying low and focusing on becoming a mom. The baby is healthy and she's so excited," the source added.
Adele had confirmed her pregnancy in June and said she wanted fans to hear the news directly from her.
