Jennifer Lopez caused some chaos when she arrived with her twins Max and Emme after a long flight from the UK on Monday. Aww they are growing up so fast! We can't believe how big they've gotten!

J.Lo went casual in a long beige coat, black top, slacks and white tennis shoes. The American Idol judge wore her hair in bun. We're not used to seeing the glamorous star looking so lowkey!

Recently, the singer has come under fire for her song "Ain’t Your Mama" because it was produced by Doctor Luke. Apparently, the singer had no idea that the song, which was written by Megan Trainor, had been produced by the under-fire music man.

According to Digital Spy, Trainor defended the superstar, saying, “I felt terrible when Jennifer got all the hate for [’Ain’t Your Mama’], and it’s just all ridiculous. It’s such a big song for her.”

Trainor said in an online conversation, “I texted her the song and she had no idea - she thought I did it alone by myself at my house, which a lot of people think because I do do that." She continued, "I sent it to her and said, Do you like the song?’ and she said, ‘I love the song, my kid loves the song - he’s made me play it five times already so I know it’s a hit - when can I cut it?’, so I said immediately, ‘Whenever you want!’”

So does that mean this is all Meghan Trainor's fault?!

Maybe Jenny from the Block should have done her research before getting into bed with the doc!
