By Splash New mum Jennifer Lopez cannot hide her devastating grief as she attends the funeral of a beloved aunt.

Even giant sunglasses do not hide the marks of her tears as the superstar singer hugs and kisses relatives at the funeral of Myrza Rodriguez in New York.

The star knew her aunt was on death's door, reportedly with cancer - but the pain etched across her face shows just how terribly hard the loss has hit her.

Jennifer's husband Marc Anthony constantly held her hand as she attended the funeral at the Church of St Ann in Ossining, New York, where her mum lives.

"She looked beyond consolation," one onlooker said.

"She had clearly been crying - a lot. It was hard seeing her so devastated."

Friends say she was incredibly close to Myrza, who was a sister to J-Lo's mother Guadalupe.

In 2005, Lopez reportedly spent $50,000 to send Myrza to Germany for experimental treatment to treat her ovarian cancer.

After she was said to have attended six weeks of alternative therapy at the Leonardis Klinik Bad Heilbrunn in Germany, Myrza had a temporary remission in her battle.

But the cancer returned last year and recent chemotherapy treatments were unable to stop the progress of the disease, according to a US magazine.

She was too weak in February to attend the baptism for Lopez's twins, Emme and Max.

And she finally lost the battle earlier this month.

Even with so much warning, J-Lo was still overwhelmed.

"Jennifer has been preparing for this, but when the time finally came, she was heartbroken and devastated and turned to Marc for support," a family source told the US magazine The National Enquirer.
