Hitting the half-century mark seems to be no big deal for Heather Locklear
– judging by her little black dress.
The eternally sun-kissed stunner, who turns 50 in September, stepped out in stilettos for Samuel L. Jackson's charity dinner in London on Thursday night, rocking the curve-hugging ensemble.
The Melrose Place
alum attended the event with her longtime boyfriend
, actor Jack Wagner, 51, who supports a healthy lifestyle for them both.
"He has been a great influence on Heather," a friend of the actress told PEOPLE in 2008
. "He's really committed to a healthy life."
