Melania Trump was ‘looking after her ailing mother Amalija, 78’ during the Mar-a-Lago Christmas celebrations and missed the family photo under the tree

Melania Trump was not seen in family Christmas photos posted to social media as she cared for her ailing mother.

Amalija Knavs, 78, is sick in the hospital, according to multiple reports — and the former first lady has been at her mother's side instead of at Mar-a-Lago to celebrate the holidays with her family.

Kimberly Guilfoyle, Donald Trump Jr.'s financier, posted a family photo to her Instagram Story the day after Christmas, showing several members of the Trump family.

What was immediately noticeable was Melania's absence from the image.

“Melania has always been very devoted to her entire family,” said a source close to the former first lady told Fox News Digital. “It should come as no surprise that she spent Christmas with her sick mother.”

Guilfoyle's photo posted to her Instagram Story on Tuesday evening showed much of the Trump crew standing in front of a Christmas tree at the ex-president's Mar-a-Lago estate in Palm Beach, Florida.

Melania's father, Viktor Knavs, 79, was present in the photo.

The photo also shows former President Donald Trump; his eldest son Don Jr. and finally Guilfoyle; the youngest Trump child Barron, 17; Tiffany Trump and husband Michael Boulos; and eldest daughter Ivanka with husband Jared Kushner and their three children, Arabella, 12, Joseph, 10, and Theodore, seven.

The tallest of the bunch is Barron, who is several inches taller than his father, who is 6 feet tall.

Reports this month indicate that Melania, 53, will increase her public appearances in support of her husband's re-election bid.

It comes after the former first lady, herself an immigrant, appeared at the National Archives on December 15 for remarks at a naturalization ceremony. She also joined the other first ladies at Rosalynn Carter's funeral last month — even though her husband was not present with the other presidents.

In addition to Melania, Eric Trump and wife Lara were also not present in the group photo in front of the Mar-a-Lago Christmas tree that was posted on Tuesday.

Guilfoyle also posted a few images to her Instagram grid with her fiancé Don Jr. and the ex-president for the festive decorations at Trump's Mar-a-Lago resort and residence.

Although they didn't spend Christmas Day together, half-sisters Ivanka and Tiffany Trump joined the family celebration on December 25.

The two also showed their festive spirit in cheerful posts shared on their respective social media accounts.

Marla Maples, 60, who was married to Trump from 1993 to 1999, posted a photo of her and her daughter, Tiffany, 30, posing in front of a Christmas tree.

The mother-daughter duo looked in all black and wore their hair down as they beamed at the camera.

“Merry Christmas from our hearts to yours,” Marla wrote on the post. “Love, Marla and Tiffany.”

Meanwhile, Ivanka shared some festive snaps on social media, posting a Christmas photo, as well as some throwback photos.

Sharing two photos to her Instagram Story, the second-eldest child of Donald's first wife Ivana and the president showed her smiling family celebrating the holidays.

In one photo Ivanka, husband Jared Kushner, both 43, and their three children – Arabella, 12; Joseph, 10; and Theodore, 7 – all posed with the former first daughter's maternal grandmother as they celebrated Christmas lunch.

Ivanka also uploaded a photo of her family later in the evening, standing in front of an extravagant Christmas tree with her father the day after Christmas.

The family dressed up for the celebration, with the mum-of-three simply adding a Merry Christmas gif to her Instagram Story.

Ivanka, who converted to Judaism because of husband Jared, posted on the first night of Hanukkah a call for people to “bring light to the world” amid the ongoing conflict between Israel and Hamas.
