Singer Aaliyah would have turned 34-years old today.

Celebrities who were close to the her tweeted in honor of her birthday. Missy Elliot, who worked closely with the late singer throughout her career, wrote, "We miss u (you) Aaliyah! It's not a day go pass we don't think of u and how your music still have a impact on the world! Rip baby girl [sic]."

Timbaland, who produced her albums, re-tweeted the message, "Happy Birthday to the beautiful Aaliyah! Our angel ... Never forgotten!" along with a link to Aaliyah’s music video for the hit song, "4 Page Letter.”

At the age of 22, Aaliyah died in a plane crash in the Bahamas, but it is evident she continues to live on in the Hip-Hop world through her fans and other artists. 

Shortly after she passed, for example, acclaimed rapper Jay-Z dedicated a song to Aaliyah titled "Miss You," which was a remix to a single she recorded before her death. In the song, he described her as being "too good for earth."

Last August, rapper Drake released a single titled "Enough Said," featuring singer Aaliyah. The single is one of Aaliyah's unreleased tracks, to which Drake added his own verses.  

"I have some great Aaliyah news coming soon," Drake told Britain's Tim Westwood while promoting his Club Paradise Tour overseas earlier this year.

It is no secret that Drake has great respect for the late singer, as he has a picture of her face tattooed on his back. He most recently got the numbers "416" tattooed on his rib cage and posted a black and white photo of it on his Twitter account to show his fans. While "416" is his hometown area code in Toronto, Canada, the four is not completely shaded in like the other two numbers, so it also looks like "116," and Aaliyah's birthday was January 16th, or 1-16.

"I just found comfort in all of Aaliyah's music and her melody choices and the things that she talks about -- and how she always conveyed these amazing emotions but never got too sappy," Drake said in an interview with online magazine Soul Culture last year, according to the Daily Mail.
