Earlier in the day, two-time gold medallist Valerie wrote about the upcoming Adams family reunion, saying: "The Adams's are about to get together. Best of luck to all non Adams's in the mix."

She then posted a picture of herself alongside younger brother Steven, saying it had been three years since she had seen "the lil bro".

Steven, who plays for the Oklahoma City Thunder, is in New Zealand during his side's NBA off-season.

The Kiwi shot putter, who is based in Switzerland, then shared another photo of her standing between Steven and another brother, and said to her over 19,000 followers on Twitter: "And people think I'm tall!!!!"
