Adrienne Maloof: Boyfriend Jacob Busch is Half Her Age, Talks About Marriage Soon

Just over one year into their relationship, the 53-year-old Real Housewives of Beverly Hills star and her heir boyfriend are reportedly on the rocks, and according to a source, socialite Paris Hilton is at the center of their problems.

“Adrienne’s boyfriend, Jacob, has been seen going over to Paris’ house, which is very close to hers,” an insider revealed to Radar Online on Nov. 6. “He never goes with Adrienne, and it’s obvious he isn’t going over there to borrow some sugar, or milk!”

Following her 2012 divorce from Dr. Paul Nassif, star of E!'s Botched, Maloof began dating Sean Stewart, who was 32-years-old at the time. Then, after about nine months together, the reality star and mother of three moved on from the son of rocker Rod Stewart, and began dating 24-year-old Busch, heir to the Anheuser-Busch brewing company.

“Jacob stops by Adrienne’s house when he knows she won’t be there, and then he goes over to Paris’ house instead,” the source claimed of Busch's relationship with the former Simple Life star. “Jacob and Paris have definitely been hanging out. Word has gotten back to Adrienne about the visits, and needless to say, she isn’t happy about it.”

In February of this year, Maloof claimed an engagement was imminent, but now, many months later, it appears this relationship is nearing its end.

“Jacob insists nothing is going on other than friendship with Paris, and has expressed nothing but love for Adrienne, but all talk of marriage is now on hold,” the source added.
