Katherine Heigl gave birth to a baby boy during the holidays, and it's only now reaching the mainstream.

Heigl and husband Josh Kelley welcomed their new son Joshua Bishop Kelly Jr. Dec. 20, according to PEOPLE magazine.

Joshua Bishop will join his siblings Adalaide, 4, and Naleigh, 8, as part of the Heigl-Kelley family.

The couple first announced they were having another child back in June of last year, saying the entire family felt excited for the newborn.

The Kelley clan is thrilled to announce that we are expecting a third addition to our family, the couple told PEOPLE in a statement back in June 2016. Naleigh and Adalaide could not be more excited to welcome their new sibling into the fold, and Josh and I are overflowing with joy and gratitude.

She said something similar to "Entertainment Tonight" in August.

"They're so excited," Heigl told ET. "For them, it's an 'out of sight, out of mind' thing. They'll forget about it for a while, and then suddenly be like, 'Hey, have you had that baby yet?'"

Heigl also launched a blog last year that highlighted her experiences with her pregnancy called Heavenly Days. She encouraged other pregnant women to read the website to gain some insight and assistance with their pregnancies.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
