Lily Allen thinks her pregnancy is "the best thing ever".
The British star's father Keith Allen recently confirmed that she is expecting another child with her husband Sam Cooper.
Lily and Sam welcomed daughter Ethel Mary into the world in November last year. Lily is said to be excited about the new addition now that she's over the initial shock.
"Now she is used to the idea, Lily is thrilled and thinks it's the best thing ever. At first, she was a bit stunned, saying: 'No way can I be pregnant,' but since it's been confirmed, she's been embracing it," a source told British magazine Closer.
"She's telling everyone: 'Well, I did say I wanted to fill the house with kids!'"
Lily has reportedly been struggling in the first trimester of her pregnancy. The 27-year-old is also said to be coming to terms with expanding her family again.
"She just didn't expect it so soon as Ethel is still very much in shock. And Lily's aware of how much she's going to have her hands full when another baby arrives in six months," the insider added. "Lily has been terribly sick and she's feeling exhausted. She's been desperate to go to bed early. She's also a bit peeved that she hasn't lost all of her baby weight since having Ethel.
"She had tried to diet a bit, but between Ethel and going back into the studio, she hasn't had a chance to do much exercise, but it's just not her priority now!"
