Taylor Swift hosted a star-studded pool party at her Rhode Island mansion to celebrate Blake Lively's 37th birthday, following the conclusion of the European leg of her Eras Tour. Notable attendees included Swift's boyfriend Travis Kelce, Bradley Cooper with his daughter Lea, Ryan Reynolds, Patrick Mahomes, and Jason Kelce. The event marked the first public appearance of Swift and Kelce together since July, and also featured Lively and Reynolds sharing a romantic moment. Bradley Cooper's current partner, Gigi Hadid, was notably absent, though Cooper and Hadid have been committed to their relationship. The party provided a rare downtime for the celebrities amidst their busy schedules, with Swift set to resume her tour in North America in October.
