New mom Tori Spelling, who just gave birth to daughter Stella on June 9, still finds time for some one-on-one time with son Liam.

The mother and son took a break from the heat by watching "Alvin and the Chipmunks" on Blu-ray Disc in the 20th Century Fox Home Entertainment MaliBlu-ray Screening Room at the DKNY Jeans Beach House in Malibu.

Tori, who currently stars in the Oxygen reality TV series, "Tori & Dean: Home Sweet Hollywood," will guest star in the updated version of "90210," airing on The CW this fall. She will be reprising the role of Donna she created in the original "Beverly Hills, 90210" series.

She recently told ET, ""I don't know much about my character. I have been in talks with the producers. I definitely want [Donna] to stay in fashion. We did talk about a boutique, but I don't think it is firm yet."
