kristen stewart robert pattinson intimate Kristen Stewart and Robert Pattinson get cozy at friend's Los Angeles birthday party

Kristen Stewart and Robert Pattinson don’t seem to be keeping their on-again romance a secret anymore. The two were spotted earlier this month at Los Angeles’s SoHo House, and this weekend they were seen at another Tinseltown hot spot: Chateau Marmont.

Us Weekly reports that the couple was there for a friend’s birthday party Saturday. A witness claims Pattinson, 26, and Stewart, 22, “snuck into the garden from a private side entrance.”

“They’re afraid of backlash, so they’re keeping things on the down-low,” a friend explains.

A second witness says that the “Twilight Saga” stars were “whispering very close and intimately.”

After spending all this time together privately, Stewart and Pattinson will finally reunite publicly later this month for “The Twilight Saga: Breaking Dawn — Part 2” press tour. The final “Twilight” film is due in theaters on Nov. 16.
