Guess Who Came To Dinner?

Courteney Cox is back in Mexico with Jennifer Aniston and her gal pals and judging by her relaxed appearance ... getting there was a lot easier this time than the last girls’ getaway.

The "Cougar Town" star splashed in the waves on the beach in Cabo San Lucas Wednesday as she celebrated her 55th birthday with some of her best friends ... including her "Friends" costar.

The other ladies enjoying fun in the sun include actress Mary McCormack, Kristin Hahn, and Jason Bateman's wife, Amanda Anka.

It's unclear if Jimmy Kimmel's wife, Molly, made this trip, but you'll recall back in February ... she was with Jen, Courteney and Amanda when they had to make an emergency landing on the way to Cabo to celebrate Aniston's big 5-0.

Thankfully, there was no such scare that we know of for Cox's bday gathering ... just nothin' but a good time.

Then Emma Watson visits Cabo for the second time this year

On Monday, British actress Emma Watson was seen in Los Cabos enjoying the sun in one of the hotels in Cabo San Lucas.

The 29-year-old British movie star wore a white bikini while relaxing on the premises next to the pool, at which point she seemed to be in a good mood; however, it is unknown if she was in the company of somebody or not.

This would not be the first time that the interpreter of Hermione Granger, in the famous Harry Potter saga, visits this destination of Baja California Sur, because in October of last year she was in the company of businessman Brendan Wallace, with whom she maintained a romance.

Loreto is another South Californian site that the British actress has visited, as she published on her social networks’ images of her experience in this magical town, where she was enjoying the sighting of the blue whale.
