Britney Spears Goes Horseback Riding for Boyfriend Charlie Ebersol’s 32nd Birthday: Pictures

Britney Spears' relationship is getting serious! The singer took her boyfriend Charlie Ebersol horseback riding to celebrate his 32nd birthday.

The 33-year-old looked anxious as she prepared to take a ride in an indoor stable with her new love on Tuesday, Dec. 30. She dressed down in jeans, a plaid shirt and black peacoat, while Ebersol wore a decorative reindeer sweater.

"Birthday horses for my birthday boy," the mom of two gushed. In a second pic, Spears showed off Ebersol's birthday cake. The festive movie-inspired treat was decked out with photos of the happy couple and stills of classic romance films like Pretty Woman and Bridget Jones' Diary. It also included popcorn and a director's clapboard with "Charlie" written on it.

"I believe it's clear that I won the birthday cake war!" Spears teased. Earlier this month, Ebersol surprised the star with her very own pink birthday cake. "Couldn't have wished for a better birthday yesterday…" she captioned an Instagram pic at the time. "Hello, 33! #Club33."

Us confirmed in November that the couple are dating. Ebersol is the son of Saturday Night Live co-creator Dick Ebersol and actress Susan Saint James.
