BRITNEY SPEARS

The Toxic singer is ending her fouryear stay in Las Vegas — and getting lots of love from her boyfriend, Sam Asghari. Asghari posted a video Monday of Spears performing the last show of her Pieces of Me residency at Planet Hollywood Resort & Casino along with a supportive caption. “4 years of legacy, 4 years of greatness, a change in entertainment for the better!” he wrote on Instagram. “Extremely proud of my baby for kicking (butt) again tonight, but this time to end #pieceofme In Vegas after 4 years of residency. What a night.”
