The Smile songstress has sparked engagement rumours after she was spotted sporting what looked like a diamond ring, reports The Sun.

The paper says Lily, 22 - who recently revealed she is expecting her first baby with the Chemical Brothers rocker - was shopping in the capital when she was seen wearing a band on her ring finger.

Earlier this week the pop star said she was "thrilled" to be expecting a baby with Ed, 37, who she started dating in September.

A spokesman for Lily said: "I am pleased to confirm that Lily Allen and her boyfriend, Ed Simons, are expecting their first child.

"However, as the pregnancy is at a very, very early stage, the couple ask that you respect their privacy, as the health of Lily and their child is their paramount concern. As the pregnancy is at such an early stage, the couple will be making no further comment but they are obviously both thrilled by the news."

The 22-year-old Smile songstress is "thrilled" to be expecting a baby with Chemical Brothers star Ed Simons, 37, who she started stepping out with in September.

"Lily’s new album will be released as planned next year."

News of the chart-topper’s pregnancy was first revealed in today’s (Wednesday) edition of The Sun newspaper.

Lily began seeing Simons after splitting from long-term boyfriend Seb Chew. The couple are planning to move into a £700,000 home in Queens Park, north-west London, next month.

BBC Three said the singer’s new TV show, Lily Allen And Friends, will go ahead as planned. Filming is likely to begin in February.

"We have heard the news and we are thrilled for her," a BBC Three spokeswoman said.

Mark and Lily ’make up’ - Dec 16 2007
Mark Ronson and Lily Allen have apparently kissed and made up - after weeks of reported feuding.

The producer helped Lily create her 2006 debut album Alright, Still - and they had stopped talking.

Mark told the Daily Mirror: "We are friends again - we’ve made up and everything is cool between us. I was hanging out with her on Tuesday night at Bungalow 8 and she was very nice."

The estrangement began when Lily didn’t show up at Mark’s BBC Electric Proms performance in October. She then ignored his calls.

However, it seems that Mark is now hopful he will work on the Smile singer’s forthcoming outing - and is keen to join her onstage at the Brits.

"I’m blackmailing her into performing at the Brits with me," he laughed. "I say to her ’I knew you when’ so she can’t get out of it."
