Kristen Stewart and Alicia Cargile may finally be on the verge of a break-up.

This, according to "OK!" magazine, quoting an "In Touch" magazine report.

It seems that the "Twilight" star is being smothered by all the attention she has been receiving from her personal assistant and wants to have some personal space for herself to sort things out.

"Things are moving too fast for Kristen. She wants to take a break," a source told In Touch.

The 25-year-old actress and her PA have been hounded by controversy since they started living together as a couple in August of last year.

But the pressure of the relationship has apparently taken a heavy toll on "The Snowman and the Huntsman" star.

"Kristen feels they made a mistake moving in together so quickly. They're together every second of the day and it's too much," the source revealed.

And going by recent developments, the pair's union isn't turning out exactly to be a bed of roses.

"They just can't see eye to eye anymore on anything," the source added.

Meanwhile, despite all the buzz surrounding Kristen Stewart and Alicia Cargile's break-up, the "Still Alice" star is regaining her old self as she made an appearance at the LA premier of her new movie "American Ultra" last Tuesday, reported Pop Sugar.

The 2010 BAFTA "Rising Star" awardee, who was joined by her "Twilight" co-star Taylor Lautner, sizzled in a revealing romper with a plunging neckline, while her partner wore a sexy scruff and a blazer that showed off his broad shoulders.

The pair's appearance at the premier is the first time that fans have the two stars together since their appearance in a Sam Smith Concert in January.

"The Runaways" actress also linked up with her co-star Jesse Eisenberg, who was promoting "American Ultra."

Kristen Stewart's rumored break-up with Alicia Cargile may actually be good for the former's career after all.
