People only just realising who Hannah Montana star Emily Osment’s brother is

There are a whole load of celebrity relatives we had no clue about, including Emily Osment and her A-lister brother.

Whether it's Emma and Julia Roberts, Jonah Hill and Beanie Feldstein or Lily and Phil Collins - fans love nothing more than finding out some of their favourite celebs are actually related.

And the same goes for Hannah Montana star Emily Osment, with people only now just realising who her brother actually is.

In a photo shared on Instagram back in January, Emily, 33, can be seen standing with her older brother, who is none other than Haley Joel Osment.

Haley, 36, is best known for his roles in Forrest Gump, Pay It Forward, A.I Artificial Intelligence and The Sixth Sense, but many had no idea that he's also Emily's sibling.

Emily started off on the hit Disney Channel show and has also starred inYoung Sheldon and The Kominksy Method.

In the image, the pair can be seen posing at a restaurant, with Haley in a suit and tie while Emily could be seen wearing a silver dress.

It's believed the pair were attending the Paramount Golden Globe Nominee Celebration in Beverly Hills, California, earlier this year (4 January).

After making the bombshell discovery, fans couldn't wait to rush to social media to share their shock, with one commenting: "Just realised that you are siblings and now I feel stupid."

A second exclaimed: "WAIT YOU ARE SIBLINGS?!!!!!! Hold ON A MINUTE?!!!!!!"

"I keep forgetting y'all are siblings. You two are simply amazing," gushed a third, while another echoed: "The cutest sibling duo I didn’t know about until a few years ago!!!"

And a fifth wrote: "How long has it taken me to remember that you two are siblings?"

On Monday (10 March), Emily was seen celebrating her 33rd birthday alongside Haley as they took their pooches out on a stroll.

The outing comes five months after Emily settled her divorce from her husband of five months, Jack Anthony.

The actress filed settlement documents with the Los Angeles Superior Court after citing 'irreconcilable differences' as the reason behind the split.

According to the documents, the official date of Emily and Jack's separation was December 7th - which is nearly two months after they first tied the knot on October 12th in a ceremony which saw Haley serve as one of the groomsmen.

Emily first announced her engagement to the 42-year-old American singer-songwriter and composer in 2023, after the pair had dated for two years.
