British rapper Professor Green is relieved Lily Allen finally announced her pregnancy this month (Aug10) - because he has been keeping his pal's secret since June (10).
The newcomer collaborated with the Smile hitmaker on hit single Just Be Good To Green and she was slated to make an appearance during his set at Britain's Glastonbury music festival.
Allen pulled out of the June (10) event when she fell pregnant and confided in her friend, urging him to help her keep the baby news out of the media.
And Green admits he struggled with the secret because he was so happy for his friend.
He tells Britain's The Sun, "Yes I knew all along. She told me when she had to pull out of Glastonbury.
"It was hard pretending I didn't know because I had to act disappointed that she couldn't perform with me, but secretly I was really pleased and excited for her."
