Reese Witherspoon definitely had a ball of a time at her friend Jennifer Aniston's 50th birthday bash, evident when the actress took a huge tumble down a flight of stairs while trying to hastily make her exit from the star-studded birthday celebrations.

The 42-year-old actress looked quite red in the face as she grasped onto a glass handrail for support and struggled to pick herself up after the fall. The 'Big Little Lies' star was partying till the wee hours of Sunday morning with gal pals Gwyneth Paltrow, Laura Dern, Sandra Bullock, and Courtney Cox, reported the Daily Mail.

Witherspoon, who had donned a pair of black sky-scraper heels with her all-black ensemble, appeared to have over-indulged as she lost her balance and fell down the staircase. The fall, which was captured on camera, showed the actress' bodyguard and an assistant look on helplessly as she made her bleary-eyed exit from the party.

Once the 'Cruel Intentions' actress was at the bottom of the staircase, Witherspoon found herself being helped by a concerned hotel worker, and after brushing off the embarrassing fall, the actress got up and promptly made her way towards her chauffeur-driven car.

Earlier in the night, the 'Legally Blonde' actress looked the epitome of glamour in a black mini-dress. The night also saw a slew of Hollywood's biggest stars piling onto the Sunset Tower hotel in West Hollywood to celebrate Aniston's birthday. 

Witherspoon's appearance at Aniston's birthday party comes on the heels of news that the two actresses will soon be starring together in the upcoming Apple TV series 'Top Of The Morning'. The show is set to follow the cast and crew of a morning news show, as well as the unique challenges they face in their profession.

The same TV series is also set to star Steve Carrell and British actress Gugu Mbatha-Raw. Speaking about the show recently, Aniston said, "I just keep pinching myself, from this to that I just don't know what to say. We started shooting about a month ago and it has been just so much fun. It is hard, it is dense, but it is so fulfilling."

Witherspoon also has the second season of 'Big Little Lies' to look forward to, which is slated to premiere in June this year. The show will directly pick up where it left things in the first season and has Witherspoon and Dern joined by co-stars Nicole Kidman, Zoe Kravitz, and Shailene Woodley, with Meryl Streep being the most recent entry.
