The mother-of-one looked stunning as she arrived for a showing of Panda! at the Palazzo on Saturday evening (11 January).
Wearing a show-stopping red satin gown, the former Girls Next Door star embodied classic Hollywood glamour and certainly turned heads at the show, which features high-flying acrobatics.
Holly walked the red carpet without husband Pasquale Rotella (who was probably at home looking after their adorable baby daughter Rainbow), but did find a cuddly Panda Bear to cosy up to instead!
Holly, who celebrated her 34th birthday just before Christmas, had a pretty amazing 2013 which included welcoming her first child and tying the knot with businessman Pasquale.
The blonde beauty became a mum in March 2013 when little Rainbow Aurora was born and cemented an already incredible year by marrying Pasquale at Disneyland California in September.
