The newest addition to the Trump circle made her official political debut on Saturday evening, as Trump's granddaughter Kai and daughter Ivanka appeared beaming at the inauguration events.
Bettina Anderson – whose romance with Don Jr, 46, was first revealed by DailyMail.com last summer – attended the family's pre-inauguration celebrations at Trump National Golf Club in Sterling, Virginia.
Anderson, 38, who has kept a relatively low profile since the exclusive report of her relationship with the former first son, appeared in a Trump family photo as they gathered for a fireworks show ahead of Monday's swearing-in ceremony.
The Palm Beach socialite's presence at the historically significant family event comes after reports that Trump allies are trying to keep her away from the historic inauguration.
Sources have exclusively told DailyMail.com that Don Jr.'s new flame isn't “MAGA enough” and that her infamous reputation as a Palm Beach party girl doesn't mesh well with the first family's A-list Mar-A-Lago clientele.
People close to the Trump family shed light on her dating history and hoped to keep her from the newly elected president's inauguration in Washington on Monday.
Meanwhile, Trump's young granddaughter Kai captivated social media with a video of her twirling in a stunning blue dress with the caption “On the way to DC.”

The 17-year-old previously revealed she is feeling slightly anxious after leaving her outfit planning until the very last minute.
In a video on her YouTube channel last week, the aspiring golfer said: 'Normally I don't get nervous about things, but the inauguration… I'm not nervous, I'm just as excited. I have butterflies in my stomach like I'm craving it.
'But I'm a little stressed because I didn't pick out an outfit in advance and now I'm thinking, “Oh! Last minute, I have to go to the dry cleaners.”
“But other than that, I'm honestly not that stressed.”
Ivanka Trump also shared photos of her family arriving in DC.
She is pictured with her husband, Jared Kushner, and their children, with the caption “2025.”

During the celebration, the president-elect and Melania Trump received an intimate performance from Christopher Macchio, who performed “Hallelujah,” “Ave Maria,” “How Great Thou Art” and “God Bless America” as the couple held hands.
Trump later showed off his signature dance moves.
Other family members in attendance included Eric and Tiffany Trump.
Michael Boulos was also spotted among the VIP guests watching the fireworks.
The indoor celebration served as a prelude to Monday's swearing-in ceremony, which has been moved to the Capitol Rotunda due to forecast cold temperatures.
Before then, Trump will lay a wreath at Arlington National Cemetery and hold a “Make America Great Again Victory Rally” in Washington on Sunday.

Both Donald Trump Jr.'s new socialite girlfriend, Bettina Anderson, and his ex-fiancée Kimberly Guilfoyle will be at the inauguration on Monday, according to the Daily Mail's new podcast, Welcome to Magaland: Inside Trump's Second 100 Days.
It has been reported that allies of the president-elect have tried to keep Anderson away, but the inauguration will be the new couple's first public event.
Guilfoyle will also be there, and – sources say – is expected to sit next to the family in her new role as US ambassador to Greece.
The VIP guests will include many names who no longer appear to be hiding their support for Trump or have switched to the Republican Party, including Amber Rose and artists Carrie Underwood and Billy Ray Cyrus.
The country's tech giants, including Mark Zuckerberg, Jeff Bezos, Sam Altman and Elon Musk, are also expected to attend.

“The 'tech oligarchy', as Joe Biden seemed to call them in his farewell speech, will all be there to support the new president,” lead US reporter Germania Rodriguez Poleo said on Friday's episode of Welcome to Magaland.
“They're all going to sit together and kind of represent this new tech American power.”
