While Robert did go drinking with a male friend this Friday night and Kristen was nowhere in sight, it doesn't necessarily mean there is trouble in paradise for the Twilight twosome.
In fact, an eyewitness tells RadarOnline that, "There were a bunch of gorgeous models standing around him, but he looked disinterested in them. He was sitting with another male friend. He almost seemed timid and shy."
And it's not as if Rob and Kristen aren't spending plenty of time together these days.
After they were separated for 64-days while Robert was filming The Rover, the twosome has been practically inseparable.
They have been on a number of outings together since Rob returned, including a visit to one of their favorite karoake bars in Los Angeles where they even posed for pictures with fans.
Later in the week, they were spotted at the driving range together and they were "laughing and flirting a lot."
Considering Rob and Kristen are reportedly living together again, it doesn't seem like such a big deal that he'd want to spend some time with his friends for one night.
Do you think it's OK for couples to occasionally hit the town without their other half?
