The One Million Years B.C. actress reached the milestone on Friday (05Sep14) and held a low-key afternoon event at The Peninsula Beverly Hills hotel in California.
Collins shared a picture of the glamorous gathering on her Facebook.com page, adding in captions, "Tea at the Peninsula... Celebrating Raquel Welch's birthday."
Welch has previously admitted she is not a fan of birthdays, saying, "Every time I have a birthday, every disc jockey in Hollywood starts yahooing (sic) it all over the airwaves. Turning 60 was not a happy time... I'm far more ready to go with the flow now because I am more accepting of myself."
