Lil Wayne suffered ''seizure-like symptoms'' on Thursday (25.10.12).
The rapper's private jet had to make an emergency landing in Texas when he suffered the health scare and he was quickly brought to a local hospital, according to TMZ.
While the exact problem is unknown, he is reported to be ''doing better''.
This is the latest trouble for the star - real name Dwayne Michael Carter, Jr. - after he recently filed a lawsuit against Quincy Jones III for using his music in a documentary film.
In the court documents he claimed he never gave permission to use his music in 'The Carter', a motion picture about him.
Songs used in the movie include hits such as 'Lollipop', 'Stuntin' Like My Daddy', 'Pussy Monster', 'Let the Beat Build', 'La La', 'Mr. Carter', 'A Milli', and 'Dontgetit' from his multi-platinum selling album, 'Tha Carter III'.
Lil Wayne claims music producer Quincy Jones' son and the other producers never asked if they could use his tunes in their project.
However, it seems he cooperated with the filming of the documentary, because he allowed cameras to follow him around.
Lil Wayne didn't like the outcome of the movie and sued over it, claiming it was a ''scandalous portrayal'' of him.
In the music lawsuit, filed by the firm of Lavely & Singer on behalf of the star, Lil Wayne asks for unspecified damages and an order prohibiting the producers from using his music.
