On Wednesday, the singer stepped out in Los Angeles for a casual trip to Isabel Marant's Melrose boutique one day after Kanye West deemed her "not cool."
Swift, 26, flaunted her stems in a svelte black mini dress as her black purse with a gold chain hung from her shoulder. The "Style" hitmaker completed her look with minimal makeup – including her signature red pout – framed by her super-short bob, which she debuted at the Grammy Awards earlier this month.
Later that night, Swift switched into an all-white jumpsuit to grab drinks and snacks with a producer pal at Maia in West Hollywood, an onlooker tells PEOPLE. Prior to heading out around 1:30 a.m., she tried the hotspot's Pink Cadillac cocktail, the source says.
Despite taking a break from the spotlight after wrapping up her 1989 tour in Australia in December, Swift has been the topic of headlines after West's new song "Famous" reignited his feud with the pop star. In the tune, featured on his new album The Life of Pablo, the 38-year-old musician raps, "I feel like me and Taylor might still have sex / Why, I made that bitch famous / God damn / I made that bitch famous," referring to that time he interrupted Swift's speech at the 2009 MTV VMAs. (The musicians later moved past the drama and became friends.)
West has claimed Swift was aware of the lyric and gave her blessing prior to the song's debut. However, Swift's rep told PEOPLE earlier this month that "Kanye did not call for approval, but to ask Taylor to release his single 'Famous' on her Twitter account," adding, "She declined and cautioned him about releasing a song with such a strong misogynistic message. Taylor was never made aware of the actual lyric, 'I made that bitch famous.'"
Swift indirectly fired back at West in her acceptance speech for album of the year at the Grammys, telling the audience to ignore people who attempt to "undercut your success or take credit for your accomplishments or your fame."
In the wake of the disagreement, West shared his side of the story during an appearance at 1Oak in Los Angeles Tuesday.
"She not cool no more," said West. "She had two seconds to be cool, and she f---ed it up."
He continued: "I called Taylor. I played her. I told her, I said, 'Taylor, I talked to my wife about it.' I said, 'How do you feel about this line, Taylor? I was like, 'Taylor, I feel like me and you might still have sex.' She said, 'Ooh, Kanye, I like that line.' Then she won her award and said something completely different."
Meanwhile, Swift has shown her support for fellow singer Kesha, who is embroiled in a legal battle with producer Dr. Luke after alleging that he sexually, mentally and physically abused her. Swift joined the ranks of stars supporting the #freekesha movement when she donated $250,000 to help cover her financial needs.
