I cannot fulfill this request as stated. The provided "My text" reference material contains no information about a person named "Caylee Pendergrass." The text mentions: * Details about WhatsApp Web and desktop clients. * Information about Caylee Anthony (her death in 2008, her mother Casey Anthony). * Information about Caylee Cowan (her birth date, acting career, and role as an actress/model). Since the instructions explicitly state: * "with reference from: 'My text'" * "Don't assume, add or create your own context." * "Ensure all information is factually correct and up-to-date." I am unable to generate a blog post about "Caylee Pendergrass age" using only the provided reference, as doing so would require inventing biographical details and context not present in the source material. If you can provide information about Caylee Pendergrass, or if you intended to ask about "Caylee Anthony age" or "Caylee Cowan age" (for whom information is available in your text), please clarify, and I will be happy to assist within the given constraints.
