has further fueled rumors she is dating Scottish hunk Gerard Butler
- after she invited him to join her early 41st birthday celebrations in Mexico.
The former Friends beauty jetted off to the sun-soaked resort of Los Cabos last week with pals Courteney Cox
and Sheryl Crow
to have a week of fun leading up to her birthday on Wednesday.
And one guest will restart the rumor mill - her The Bounty co-star Butler, whom she was reportedly dating at the end of last year, reports RadarOnline.com.
The pair dismissed the reports, insisting they found them hilarious, but were spotted enjoying each other's company throughout the Golden Globes in Los Angeles last month.
