Spears, 26, wore her pink wig as she and photographer Adnan Ghalib, 35, arrived in a black SUV at the Rosarito Beach Hotel, just south of the Border, at about 3 p.m. Wednesday, according to the Ensenada, Mex., newspaper, Frontera.
Ghalib's own photo agency, Finalpixx, has been photographing the pair's Mexican activities – one picture shows Ghalib hand-feeding whipped cream from a Starbucks cup to the pink-wigged Spears – and posting online updates.
"Britney Spears and Adnan Ghalib are happily dating," the agency says in a post. (The agency notes that Ghalib "is married but has been separated from his wife for over a year.")
The pair have been together for much of the last week.
"After being released from the hospital Britney and Adnan spent the night and the following days together resting, eating, sleeping, shopping and talking about life and the love they have for their families," Finalpixx says, adding that Ghalib, himself, has not spoken publicly because it would "not be of benefit to her for him to do so."
"Should he choose to speak about Britney," Finalpixx continues, "he only has positive things to say about her and the time that they have spent together."
As for the other paparazzi chasing after them, "Despite such heavy scrutiny, the pair are enjoying a healthy, normal relationship," Finalpixx says.
Shopping Trip with PaparazzoWhile at the Rosarito Beach Hotel, Spears stopped in a gift shop and purchased an imitation Gucci bag and another bag while Ghalib bought a rosary, spending a total of $60, Frontera reports.
"She looked serious and haggard," a sales clerk told the paper in Spanish. "She didn't have makeup on."
The pop star has been in continuous motion since she lost child-visitation rights and was released from the hospital from a mental-health hold after a police standoff.
Spears went to Palm Desert with Ghalib and cruised around at night in her car, only to get a flat tire and have the car impounded.
