India, Oct. 7 -- Actor Nicole Kidman and country singer Keith Urban made separate public appearances over the weekend - their first since they announced their divorce. Nicole attended amfAR's charity auction in Texas (US) on Saturday, E! News reported. The 58-year-old wore a black off-the-shoulder dress at the event, which raised funds for HIV/AIDS research. The actor also presented Yellowstone creator Taylor Sheridan with the Award of Inspiration. Meanwhile, Keith (57) performed in Virginia as part of his ongoing High and Alive World Tour, as per TMZ; the singer has been touring since May this year. Interestingly, during the performance, Keith changed the lyrics of his song The Fighter. The track's original lyrics, which were inspired by Nicole, read, "When they're tryna get to you, baby I'll be your fighter." However, on Saturday, country singer crooned, "When they're tryna get to you, Maggie, I'll be your guitar player." Keith has been romantically linked to his touring guitarist, Maggie Baugh (25). The development surfaced soon after the news of his split from Nicole became public. Later that day, Maggie shared a video from the concert on her Instagram Story and wrote, "Did he just say that? (side eye emoji)," further fuelling speculation. Nicole filed for divorce from Keith on September 30, citing "irreconcilable differences". Sources close to the couple told People that the two had been separated for months prior to the filing and that the divorce was a result of Keith's infidelity. The two got married in 2006 and share two daughters. htc...
