Paris Jackson played the attentive girlfriend as her boyfriend, Chester Castellaw, graduated from Berkeley high school in a ceremony held at the Greek Theater in Los Angeles on June 12.

"Paris smiled for the entire day. She ran straight over to Chester and hugged him when he picked up his diploma," the source said via Daily Mail.

Paris Jackson joined her boyfriend's family as they celebrated the occasion. The parents toasted champagne for Chester Castellaw's graduation but Michael Jackson's daughter settled for bottled water.

"Paris looked neat and pretty while dressed in a black patterned top, her dark fuchsia-streaked hair shining in the afternoon sun," the British tabloid said.

"Her wrists were adorned with a cluster of amulet bracelets as she wrapped her arms around Chester's neck - he, of course, wore the robe and cap of a graduate."

Accordingly, Paris Jackson's boyfriend-although billed as a soccer player-actually is a "very smart kid."

"Chester has a healthy lifestyle and loves working out but his real passion is for sciences," the source said.

The graduation report came on the heels of the rumors that Chester Castellaw will ask Paris Jackson's grandmother for her hand in marriage.

Radar Online reported that things are getting serious between Paris Jackson and boyfriend Chester Castellaw even if they are only dating for a few months.

It said, "According to a source close to the Jackson family, the 17-year-old daughter of the late King of Pop, Michael Jackson, and her boyfriend, Chester Castellaw are so serious that they have already began discussing wedding plans - and asking her guardian, Katherine Jackson, for her blessing to marry!"

Paris Jackson's personal life couldn't be happier. While dating Chester Castellaw for a few months, her relationship with mother Debbie Rowe is as strong as ever.

A source described to InTouch Weekly, per Music-News Paris Jackson's relationship with Debbie Rowe, "They talk all the time. They see each other almost every weekend."

"Paris and Debbie are in a really great place. Their bond is really powerful," the article added.

Although Debbie Rowe was her biological mother, Katherine Jackson has full custody of Michael Jackson's daughter and her two brothers when the Prince of Pop died in 2009. Their cousin, TJ, was appointed co-guardian.
