Lady Gaga best-paid celebs under 30

Lady Gaga has been named as the best-paid celebrity under the age of 30. 
The 'Judas' singer topped Forbes' list of the Best-Paid Celebrities Under 30, reportedly earning $90 million over the past 12 months.
Justin Bieber took second place, with $53 million in earnings in the past year. The popstar was followed by Miami Heat basketball player LeBron James. The athlete has netted approximately $48 million since May 2010, largely due to the sales of his NBA jersey, as well as his bestselling basketball shoe. 
A number of other singers were mentioned on the list, including Rihanna, Katy Perry, Taylor Swift and Beyoncé. 
Twilight stars Kristen Stewart and Robert Pattinson were also featured, tying for 16th and 17th place. The two actors are estimated to have earned $20 million in the past 12 months. Both are expected to remain on the list next year with the release of the two parts of Breaking Dawn. 
Meanwhile Gaga has claimed that she writes her best songs just as she is about to drift off to sleep.
The 25-year-old performer, who set a global record for the fastest-selling album of 2011 with her new record Born This Way, revealed that she is constantly thinking about new songs, especially as she is about to fall asleep.
"I just have to [write songs]. Sometimes in the middle of night when I'm falling asleep I have a lot of ideas, then wake up and record them into my phone and send it to my producers and then I fall asleep," Gaga told The Paul O'Grady Show.
