Throughout the series she keeps her alias as Hannah Montana a secret from the world, but eventually tells several people throughout the show such as Lilly, Oliver, Siena, Jake, and Jesse.
In an off-handed remark in "Song Sung Bad," Jackson implausibly suggests the reason for this move involved an embarrassing incident with a Tennessean girlfriend.
In "Once, Twice, Three Times Afraidy", she gazed at Tim, an old friend from camp, causing Oliver to point to the menu on the side, showing his muscles.
In the Season 3 episode "Uptight (Oliver's Alright)", it is mentioned that Lilly had a crush on her French teacher during 7th grade.
They make-up again after Rico helped them get back together by writing a fake poem and send it to Lilly but signed as "Oliver Oken."
In the episode "Judge Me Tender", Oliver's singing career takes off, but all the attention he receives causes him to neglect Lilly.
He uses the alias Mike Standley III while attending events with Hannah Montana in order to keep Miley's secret.
He makes a brief appearance in Hannah Montana: The Movie at Lilly's sweet 16th birthday party and in the credits doing the Hoedown Throwdown.
Oliver later dates his classmate Sarah (Morgan York) with whom he is assigned a school project in which they must raise an imaginary child (a sack of flour).
For years, the two were best friends, but after a beach party they decided to start dating and we first see this in "What I Don't Like About You" while Miley was away shooting her feature film Indiana Joannie.
They make-up again after Rico helped them get back together by writing a fake poem and send it to Lilly but signed as "Oliver Oken".

When Miley reveals herself on television as Hannah, Rico is shocked and horrified that he could not see the obvious, unable to talk to anyone afterward.
When Miley reveals herself to be Hannah, Jackson at first gloats over Rico not knowing the secret but takes pity on him and cheers him up by having a choir sing of all the other people who did not figure it out.
She later worked as a security guard, and while on duty at a place called "Wig City", she met Miley and Robby for the first time.
Among her special abilities are dicing a pineapple with a karate chop, crushing a baseball into fine powder, and squeezing through air ducts.
They are typical school divas, aka the mean girls, very popular among their peers and spoiled by their parents' money.
This gives Miley a small taste of why she maintains her Hannah secret, as Amber and Ashley only want to be her friend for selfish reasons.

Hannah once went to Traci for boyfriend help when she asked to use her "faux-beau" to fool Lilly and Oliver (who believe that Miley is alone now that the two are dating).

Paul returned in the episode "Killing Me Softly with His Height" in the role of Dontzig's sister, "Donna", who is a huge Robbie Ray fan.
Susan B. Stewart (portrayed by Brooke Shields; seasons 2–3) was Robby's wife and Miley and Jackson's mother.
"[23] Susan was a supportive parent, but she was stricter than Robby and wouldn't let the children have sugar before bed because it gave them nightmares, as seen in "I Am Hannah, Hear Me Croak".
[24] In "Super (stitious) Girl", it is learned that Susan gave Miley a special ankle charm bracelet which says "Dream".
Robby admits that he misses Susan, and when she died, he didn't think he could raise the kids by himself, but he found the strength by feeling her presence with him.
To make her father thankful for Jake, she pretends to like her bad boy bandmate Jesse, but gets in over her head when she starts to have feelings for him so it is up to Robby to help Miley listen to her heart and chose the guy who could "be the one."
Jesse ends up figuring out that Miley is Hannah before she could even tell him, claiming that "You both have the same beautiful eyes and amazing smile."
