While honing their respective solo projects, Lil Wayne and Juelz Santana will expand their mixtape collaboration, I Can't Feel My Face, into a full album, due early next year.

"Me and L are like brothers," Lil Wayne tells Billboard.com. Santana adds, "We had a mixtape that leaked in the streets and there's a big demand. He's on fire, I'm on fire and I respect him on a musical level as well as a friendship level. It's the same vice versa so we thought we might as well get together and make it happen."

Santana has all but completed his next solo album, the follow-up to 2005's What The Games Been Missin', which has sold 655,000 units in the United States, according to Nielsen SoundScan. "I have about 75 songs done," he says. "I like to do 100 or more songs and pick [tracks] out."

Lil Wayne is also working on his next album, Tha Carter III and a collaboration set with rapper Baby, Like Father, Like Son, is due Oct. 10. The first single is "Stuntin' Like My daddy." Wayne will also launch a line of women's jeans called W Jeans, which he likens to Nelly's Apple Bottoms.
