On Saturday night, Sasha and Maisy were spotted at Miami restaurant STK in South Beach. Sasha and her squad spent the evening dining and listening to music spun by DJ Danny Stern.

During her weekend away, Sasha frolicked in the sunshine and showed off her true patriotism in style. Malia's younger sister was spotted keeping it cool and on trend in a blue and white star-patterned bikini, which she covered up with a denim frock.

Ahead of her trip, Sasha was noticeably absent from her father's farewell speech last week in the family's home state of Illinois. During her final appearance on the Tonight Show with Jimmy Fallon, Michelle explained her daughter's absence.
