It seems Rihanna has taken the recent lawsuit by a fan over allegedly contracting herpes from a RiRi Woo lipstick in stride, choosing instead to send her condolences to Bruno Mars after the death of his mother.

According to Hollywood Life, Mars' mother Bernadette Hernandez, 55, passed away after suffering a heart attack on May 31 and a brain aneurysm on June 1.

Since then, the 27-year-old singer has received much support from celebrities on Twitter.

Sending my love and condolences to @brunomars at this difficult time! I'm sincerely praying for you bro! #1Love

Our thoughts go out to Bruno Mars' family.

For Rihanna, using Twitter to focus on her tour and supporting fellow stars seems to be the way to go instead of on the lawsuit caused by her sponsored MAC product or her recent split from Chris Brown.

The herpes incident occurred during a Rihanna concert event, where fan Starkeema Greenidge of Harlem sampled a RiRi Woo lipstick with the help of a MAC employee.

"[She] didn't use a fresh or new lipstick tube, but rather one that had been used for other patrons," accused Greenidge, which is reportedly how she contracted herpes sores a few days after.

"This is going to happen over and over again if nothing is done."

So far, Rihanna has not commented on the lawsuit.
