The 'The Originals' star's engagement comes just months after she split from her husband Matt Kaplan.
Claire married the TV producer, her longtime boyfriend, in April 2016 after getting engaged in July 2015, but he filed for divorce in April, citing "irreconcilable differences", and she responded in May 2017, asking for her name to be changed back to Holt.
The 29-year-old actress - who plays Rebekah Mikaelson in 'The Originals' - appeared to confirm she was dating Andrew in July when she posted a number of pictures of their holiday in Italy and described the time as the "best month of my life".
She wrote: "Finally homeward bound after the best month of my life. Thanks for the memories! (sic)"
Real estate executive Andrew and Amanda were said to have dated for around a year but they called time on their romance in 2012.
The pair were spotted getting close at the US Open tennis tournament in August 2011.
A source said at the time: "They were very close at times. No one saw them kiss, but they were definitely cute and he was getting her drinks."
