The actress/singer, 27, posted one on Instagram, writing, “#nailingit.”
Then another, captioning the pic "Look back at it…"
Rivera's mini-break follows numerous reports that she was fired from the hit FOX show because of a feud with co-star Lea Michele, along with being dropped by her record label.
Rivera's rep denied all rumors, telling UsWeekly.com, "To be clear, any rumors or statements made as fact, that Naya Rivera was fired or let go from ‘Glee’ or dropped from her recording contract, are categorically false.”
The rep continued, "Someone obviously has an agenda to damage Naya's good name and the media are failing at their duty to responsibly vet their sources and verify what is true and what is not. Naya's attorneys are prepared to take any and all legal action to enforce and protect her rights."
Coincidentally, Michele posted her own thong bikini pics while on vacay in Mexico in January.
