Lady Gaga turns heads on ‘Artpop’ tour. Kerr and Bloom split up.

In today’s fashion roundup: Lady Gaga goes to Berlin, Miranda Kerr and Orlando Bloom split, and Barneys is accused.

Lady Gaga took to the streets of Berlin on Thursday looking like her old self. Lately, she’s been strangely demure in many public appearances, but Thursday she was back to Gaga-normal. Which is to say she was wearing a large, triangular, mask/headdress that hid her face almost completely as she traversed the streets on her tour to promote her new “Artpop” album. [The Cut]

An online petition drive on change.org is calling on Jay Z to cancel his holiday collaboration with Barneys New York after two separate incidents this week in which the retailer was accused of racial profiling young black customers who were questioned by police after making expensive purchases.

Say it isn’t so: E! reports that cute couple model Miranda Kerr and actor Orlando Bloom are breaking up. [E!]

Thursday was quite a party night. Consider:

--Audrey Tautou, January Jones, Freida Pinto, Alek Wek and Alice Dellal were among the guests at a party in Paris on Thursday celebrating Isabel Marant’s capsule collection for H&M. [WWD]

--Dianna Agron, Glenn Close, Renee Zellweger, Lauren Hutton, Coco Rocha, Olivia Munn, Ellen Barkin, Jamie Tisch, Leonard DiCaprio and Ricky Martin were among the luminaries at Giorgio Armani’s “One Night Only” party in New York City. [WWD]

--Robert Pattinson and Isla Fisher were among those attending the Australians in Film Awards in Los Angeles. (No, Pattinson isn’t an Aussie; he was a presenter.) [E!]
