Fergie caught a flight out of Los Angeles International Airport on Thursday night, and is it just us, or is Axl's mama looking better than ever? From her fit bod to the glow on her face, motherhood really suits Fergie Ferg!

The singer, who turns 40 next month, wasn't joined by hubby Josh Duhamel or their 16-month-old son, so we have a feeling this was a biz trip. Earlier this week Fergie hit the recording studio to work on her second album, which is due out later this year.

"My husband and I made a two-week rule," she recently told Allure. "We've already talked about how we're going to have to trade off. He's going to have to come on tour with Axl for a while, and then there'll be a break. He'll take a job; I'll be on set with [Axl]. You know?"

Seems like it's working quite well!
