Bobbi Kristina Brown is celebrating the holiday weekend with her 23-year-old fiance Nick Gordon and reveals she's "happier than ever."

The 20-year-old daughter of the late Whitney Houston shared photos on Twitter as she enjoyed the Fourth Of July holiday on the beach in New Jersey with family and friends.

One photo shows she and her fiance embracing on the boardwalk with the caption: "Yes... I'm MADLY in love with this phenomenal man @Nickdgordon, truly happier then ever."

She followed up by writing: "My gorgeous fiancé @nickdgordon & I on the boardwalk."

The pair were inseparable as they celebrated the 4th of July and didn't seem to mind taking photos with fans on the Asbury Park boardwalk.

Although Bobbi and Nick are not biologically related, they grew up together in the same household because Whitney reportedly informally adopted Nick at a young age.

Last year, Bobbi revealed that she and Nick are engaged in the Lifetime reality show The Houstons: On Our Own.

Bobbi's mother Whitney, at age 48, was found dead in her hotel room in Beverly Hills on February 11, 2012 after accidentally drowning in her bathtub.
