Britney Spears was spotted eating the same meal at the same restaurant twice in Las Vegas recently. After having a vacation for three months, the "Work B---h" singer is now back to her "Piece Of Me" show.

Wearing a baseball cap, a coral tube top and short shorts, Spears was first seen having dinner at the Palazzo Hotel's SushiSamba eatery. Before her show, the 32-year-old pop star had sea bass and tuna.

"Britney looks better than ever," a source from the eatery told New York Daily News.

On the same day, the fourth leg of "Piece Of Me" kicked off at The AXIS auditorium in Planet Hollywood Resort and Casino.

The next day, Spears was dressed in a pink romper when she was seen again at SushiSamba with her mother eating sea bass and tuna. She reportedly placed an order for room service, as well.

Meanwhile, on her day off from her Las Vegas residency, Spears was seen having lunch with her 28-year-old boyfriend David Lucado in Calabasas, Calif., Daily Mail reported.

Wearing a green sleeveless blouse, a pair of tiny khaki shorts, beige cork platform sandals and a pair of stylish white sunglasses, Spears had her blonde hair pulled back as she walked out carrying an iced green drink.

On the other hand, Lucado was in a white T-shirt, grey trousers, a beige newsboy cap and mirrored sunglasses.

Prior to her day off, Spears was accused of lip-syncing again during her Las Vegas show, but this time, to someone else's voice.

While singing "Perfume," the audience reportedly heard Sia's voice instead of Spears' over the speakers, Gossip Center reported.

Nevertheless, Spears' rep denied the allegations and insisted it was really Spears singing.

Produced by will.i.am and co-written by Spears and Sia with Christopher Braide, "Perfume" is the second single released by RCA Records from Spears' eighth album "Britney Jean" in 2013.
