The 25-year-old singer documented the event on Instagram as she celebrated with her younger sibling at the University of Notre Dame in South Bend Indiana.

In a video post on the picture sharing site, the blonde beauty points the camera at a guest speaking on stage before turning the lens towards her face saying: "Yeah Austin!"

Taylor clearly enjoyed her day out as she captioned the clip: "AUSTIN JUST GRADUATED FROM NOTRE DAME WHAT A DAY (sic)."

The 'Blank Space' hitmaker ensured she had time to celebrate with her brother in the midst of her busy schedule which included a performance at the Rock in Rio concert in Las Vegas on Friday and she is set to return to the city for the Billboard Music Awards this evening (17.05.15).

She and her close pal Ed Sheeran are said to have planned a huge bash following the awards and have hired out the £34,500-a-night Nobu Villa in the Caesar's Palace hotel.

The 10,500ft venue has its own bar, sauna and rooftop garden with whirlpool tub, and is expected to play host to the likes of Hozier, Lorde and Taylor's boyfriend Calvin Harris.
