Keys' online birthday tribute from fans

Alicia Keys was brought to tears as she celebrated turning 30 on Tuesday after a group of devotees created a website dedicated to her special day.

The R&B star was sent a link to happybirthdayalicia.tumblr.com to mark her milestone and the No One hitmaker admits she welled up when she saw the online tribute.

Taking to her Twitter.com page, the birthday girl writes, "OMG (Oh my god)! I'm over here crying from this beautiful & thoughtful site u guys did 4 me! U mean so much 2 me (sic)!"

The website features blog posts, video messages, song dedications, artwork and photos from fans around the world, all expressing their love for the new mum, and wishing her a very happy birthday.
