Leighton Meester isn't spreading any gossip here.
Rather, the Gossip Girl actress, 25, is getting the word out on the importance of registering as a bone marrow donor to help in the fight against blood cancer.
And what better way to do that than to lead by example?
Sure enough, Meester herself got swabbed in New York City on Tuesday as part of the registration process.
The move comes just days after a new PSA was released by DKMS, the world's largest bone marrow donor center, in which Meester teams up with 19-year-old blood cancer survivor Kerri Mullen to encourage folks to join the Share the Love campaign.
"Share the Love is an altruistic idea of love—it's about giving the gift of life to a stranger," Meester says in a statement. "You can register as a donor by going to GetSwabbed.org. It's easy, and the more people who get swabbed and are willing to donate, the more lives we can save -- and that's pretty incredible."
