Swift tweeted, “Sang Jenny From the Block with @JLo tonight at Staples Center. STILL FANGIRLING OUT ABOUT IT.”
Just the night before, Judd Apatow and Leslie Mann brought their daughter Maude to see T. Swift in concert. “Leslie and I are so proud of our new daughter @taylorswift13,” Apatow cracked on Twitter with a photo of the trio.
