Miley Cyrus and Patrick Schwarzenegger might be engrossed in each other, but he might lose a lot if he continues to date her.

Miley Cyrus Claims Patrick Schwarzenegger Is 'Da Best BF Eva' On Instagram

The couple has been pretty inseparable since they began dating in late 2014, but Schwarzenegger's family apparently remains unhappy about his choice of girlfriend.

Multiple reports have surfaced over the last few weeks about his mom, Maria Shriver and his dad, Arnold, being unhappy about him dating Cyrus. 

Miley Cyrus & Patrick Schwarzenegger Rang In 2015 Together

Hollywood Life reported in early December that Schwarzenegger's parents panicked over their son spending so much time with the Wrecking Ball singer especially when they were in Miami Beach together.

A source told the site, Schwarzenegger's parents are "very afraid" that all their time spent together could lead to bad ideas.

"Maria is terrified Patrick's going to do something insane," the source divulged.

Just days ago, Cyrus rang in 2015 with Schwarzenegger and his dad as reported by People, but it appears as though Arnold and Shriver are still unsettled about Cyrus being with their son.

AZ Central reported Sunday that Schwarzenegger's parents have given him an ultimatum.

A family friend revealed Schwarzenegger could lose his $49 million trust fund if he remains in a relationship with Cyrus.

"They [Maria and Arnold] are both convinced she is a negative influence on their son and are determined to end the relationship," the family friend shared.

Schwarzenegger apparently would rather lose the trust fund than Cyrus though.

The source added, "Maria especially is hoping the shock tactic of threatening to cut him off financially will scare him into giving Miley the elbow."

Plus, on Monday The Sun reported they obtained a photo of the singer from a recording studio session in November, in which drug paraphernalia, which will surely not sit well even more with Schwarzenegger's parents, surrounds her.
